I want peppy do that PPv2 depends on SPINNERS!!! #1 in "your" mod - much more pp.
Bad english, yea...
though i got nub spin

Spinners are fine as they were before the non-functional "update". Well, maybe they had a somewhat too high influence on PP but I guess it's too difficult to neglect that when it comes to rankings & stuff.
Example:
A : 5650 Score
B : 5649 Score (1 Spinner less than A)
C : 5647 Score (2 spinners less than B, 3 less than A)
D : 5644 Score (3 less than C, 6 less than A)
E : 5640 Score (4 less than D, 10 less than A)
Let's assume they have all HD 100%.
I think A would get way more PP than the rest in the last sytsem (while D would get next to no PPs) which had to do with the rankings of the map. I can't think of a way to make the spins' influence lower.
More interesting in terms of spins are the following two:
No-spinner-map:
A, B, C & D: 5650 Score, HD 100%
E: 5650 - 10 Score, HD 99,xx%
Here, E'd get absolutely no PPs for FCing the map since he didn't get SS while A - D would get the full amount of PP since they're theoretically all on the same position in terms of ranking.
It'd be much easier if there would be a definite PP for Rank X - Y (100%) on zero-spinner-maps and a penalty for those who didn't get SS, but not that huge.
Another one's this:
A: 5651 Score, 100%
B: 5650 - 10 Score, 99,xx%
C: 5649 Score, 100%
A'd get the most PP here, that's for sure I guess, while I think C'd get more PP than B because he got 100% on the map.
That's a pretty basical problem the new system has to deal with - what's worth more? 100% or more spin?
It surely has been 100% in the old system.

I guess you can leave OD out of this discussion because it doesn't affect the ctb gameplay.
Another thing to add: Do not give more pp for ctb difficulties, they should be rated as every other map, as some people said, there are some non-specific maps that are way harder than ctb specific ones.

I never agree. SS is easy in CTB compared to other modes, of course. But then how can you give an explanation that old map, for example? There are many map for weird sliders and small CS. In some map of them, it is more hard to rank SS in CTB rather than other modes. rank higher accuracy is great abillity too. I hope to don't overlook that. In addition, if make less weight of SS, how many users strive to do rank SS? Then many users will be don't really work to do rank SS but just aim to FC and spins. How could be SS FC same with S or A, B, C, D FC on the earth?TenguKing9 wrote:
I have a few suggestions that I would like to give for this system:
1. As DeathXHunter said before, SS should have less weight in the formula since it's easier to SS in Catch The Beat compared to other modes.

2. Since FL is heavily based on memorization rather than actual skill it should be weighed a bit less than no mod plays.
FL just only need memorization? How many did you played FL? Especially, i want to ask you about have you played FL on AR 7, 8, 9 maps. To jump to the conclusion about FL is heavily based rather than actual skill, "No". I guess you don't know about what is FL actually. FL needs many actual skills. Many FL on AR 6- map maybe just need memorization. But so did AR 7+? As like AFB says, FL mod makes some black areas (Invisible) around the ryuuta. And the areas dimished when you catch the fruits 100, 200+ combo. You can never see any fruits on black areas. you can just depend on narrow lightning (Visible) areas. So you will be feel higher AR when you playing FL on whatever map. As you know, when you add HR or DT, that makes AR higher. FL so does. When you playing FL, you have to make combo in limited sight. It needs memorization, control, and adapt to higher AR. Bonus score is higher in HD+DT than FL but FL is very difficult in many AR7+ maps than HD+DT. Please play FL on AR7+ maps and think about why FL players are fewest in 4 modes.alienflybot wrote:
FlashLight (FL) - In my opinion this would be the mod that gives the least pp. FL tests player's memorization, which is just acting the same thing as No-Mod does, but with some black areas around the ryuuta. I think using FL just only need memorization, which should not worth that many pp.
Therefore, i disagree absolutely about make less weight pp of SS and FL on ppv2! They're have to keep on going like ppv1!
- My opinion
DeathXHunter
Totally not biased *cough* http://puu.sh/6HeMy.png
He said it should be less considered than it is in ppv1 and not totally ignored because it's infact the easiest mode to get an SS. About FL,I don't care,it's shit anyways.

Pessimism everywhere...
Have you ever tried to be SS player and FL? It's just like someone who can't pass some beatmap criticizes like 'OMG THIS MAP IS SHIT'
I said that as a CtB player, not as a Korean.
I'm not a pro FL player so I won't, but about the SS, I think setting the players' most frequency droplet misses as a point criteria is better.
Some maps are easy, but some maps (especially maps in 2008~2009s, http://osu.ppy.sh/p/beatmap?b=6097&m=2)are hard to SS.
Users' frequency Percent of pp Droplet misses
50%(the most) 10% 3
20% 13% 2
10% 20% 1
2% 30% 0

Aight then
So there should be a function that can calculate what mod the player rely on.
For example:
(A player's records)
HR FC - 20
DT FC - 10
HD FC - 55
FL FC - 200
So he relied on FL more than the other mods, so when he uses FL on the other maps/diffs, he may get less pp than using other mods.

FL is the hardest mod so far in AR9+

AF = Acumulated Frequency of all groups with less droplet misses
DF = Diminishing Factor (where 0 < DF < 1)
BPF = Best Performance Factor (BPF > 1, here it is assumed that BPF = 1.01)
This seems like a good idea. And it can be worked, and here's an way: plays are sorted by droplet misses and the frequency of users with 'x' droplets misses is calculated. For the group with less droplet misses, pp given (BestPP) might be calculated as BestPP = MaxPP/BPF^(Droplet Misses). For the following groups, PP might be calculated as PP = floor(BestPP*(1- AF)^DF) (you'll see the reason for this DF later)
I'll do 4 examples, two assuming DF = 1 (Case A) and two assuming DF = 0.1 (Case B). In both cases, one example will be with players having 0 droplet misses and the other one with best plays having (at least) 1 droplet miss. Also, we'll assume the maps gives 100pp max and all scores are FC no mod.
Case A: DF = 1
A-1: There are plays with 0 droplet misses, so we'll consider the following distribution:
Group Class Users' frequency Droplet Misses
F 10% 5
E 15% 4
D 30% 3
C 25% 2
B 15% 1
A 5% 0
Group A would get 100pp (max possible, BestPP = 100/1.01^0 = 100)
For Group B, AF = 5%. So, PP_B= 100*(1-0.05) = 95
For Group C, AF= 5% + 15% = 20%. Therefore, PP_C = 100*(1-0.2) = 80
Similarly, PP_D = 55, PP_E = 25, PP_F = 10
A-2: Best play has (at least) 1 droplet miss, so we'll consider the following distribution:
Group Class Users' frequency Droplet Misses
E 10% 5
D 15% 4
C 30% 3
B 25% 2
A 20% 1
Group A would get BestPP = 100/1.01^1 = 99 pp
For Group B, AF = 20%. So, PP_B = 99*(1-0.2) = 79pp
Similarly, PP_C = 54, PP_D = 25, PP_E = 10
PP diminishing for missing droplets seems to harsh, so now I'll repeat the whole process considering DF = 0.1:
Case B: DF = 0.1
B-1: There are plays with 0 droplet misses, so we'll consider the following distribution:
Group Class Users' frequency Droplet Misses
F 10% 5
E 15% 4
D 30% 3
C 25% 2
B 15% 1
A 5% 0
Group A would get 100pp (max possible, BestPP = 100/1.01^0 = 100)
For Group B, AF = 5%. So, PP_B= 100*(1-0.05)^0.1 = 99
For Group C, AF= 5% + 15% = 20%. Therefore, PP_C = 100*(1-0.2)^0.02 = 97
Similarly, PP_D = 94, PP_E = 87, PP_F = 79
B-2: Best play has (at least) 1 droplet miss, so we'll consider the following distribution:
Group Class Users' frequency Droplet MissesGroup A would get BestPP = 100/1.01^1 = 99
E 10% 5
D 15% 4
C 30% 3
B 25% 2
A 20% 1
For Group B, AF = 20%. So, PP_B = 99*(1-0.2)^0.1 = 96
Similarly, PP_C = 93, PP_D = 86, PP_E = 78
Some ideas left:
* BPF could change based on the difficulty of catching all the droplets: maps where catching the droplets is harder should have a lower BPF
* The term BPF^(Droplet misses) could be capped at some value, e.g., 1.1.
* How can this be incorporated considering all other variables (accuracy, spinners, mods)? Maybe it could be a percentage of "accuracy".
PS: Sorry if I made any mistakes while writing this!
EDIT: Just noticed this doesn't work for certain cases. Gonna think about it later
EDIT2: Ok, I think I got it. The special case it wasn't going to work was when there's a group class with ~0% frequency, as that class and the next one would get almost the same ammount of pp (thus making catching that extra droplet worthless).
UPDATE
The new approach I'd try would be: for each class, calculate its max pp possible (TopPP) according to droplet misses, using the same formula for BestPP, i.e., TopPP = floor(MapPP/BPF^(Droplet Misses)). Now, for each class, calculate its real pp using a diminishing formula based on acumulated frequency, as PP = floor(TopPP*(1-AF)^DF).
Now, I'll use one of the examples from above but calculate map pp worth using those new formulas. Also, I'll show one case of a harder to SS map.
Example 1:
Group Class Users' frequency Droplet Misses
F 10% 5
E 15% 4
D 30% 3
C 25% 2
B 15% 1
A 5% 0
TopPP_A = floor(100/1.01^0) = 100
PP_A = floor(100*(1-0)^0.1) = 100
TopPP_B = floor(100/1.01^1) = 99
PP_B = floor(99*(1-0.05)^0.1) = 98
TopPP_C = floor(100/1.01^2) = 98
PP_C = floor(98*(1-0.2)^0.1) = 95
TopPP_D = floor(100/1.01^3) = 97
PP_D = floor(97*(1-0.45)^0.1) = 91
TopPP_E = floor(100/1.01^4) = 96
PP_E = floor(96*(1-0.75)^0.1) = 83
TopPP_F = floor(100/1.01^5) = 95
PP_F = floor(95*(1-0.9)^0.1) = 75
Example 2: This is a harder to SS map, as there are 5% user with 0, 1 or 2 droplets misses.
Group Class Users' frequency Droplet Misses
F 30% 5
E 40% 4
D 25% 3
C 4% 2
B 0% 1
A 1% 0
TopPP_A = floor(100/1.01^0) = 100
PP_A = floor(100*(1-0)^0.1) = 100
TopPP_B = floor(100/1.01^1) = 99
PP_B = floor(99*(1-0.01)^0.1) = 98
TopPP_C = floor(100/1.01^2) = 98
PP_C = floor(98*(1-0.01)^0.1) = 97
TopPP_D = floor(100/1.01^3) = 97
PP_D = floor(97*(1-0.05)^0.1) = 96
TopPP_E = floor(100/1.01^4) = 96
PP_E = floor(96*(1-0.3)^0.1) = 92
TopPP_F = floor(100/1.01^5) = 95
PP_F = floor(95*(1-0.7)^0.1) = 84
When the map is harder to SS, less players concentrate on classes with less droplets misses and the decreasing factor based on AF is not that harsh.
Two-three days ago I was 100K+ rank now 21K(according to bancho bot IG).
And honestly I'm not the best player but I always aim for the S rank.
It could use a nerf because its now really easy to get a decent rank while you suck(reffering to myself
)

Uh I'm going to try to reply to zirox's post 
. I think the idea looks good, if I understand correctly you are calculating a maximum droplet pp contribution based on the map's difficulty. Then a player will get a higher fraction of that if it's more difficult to catch all of the droplets on that map. Also that droplet contrib would have less weight if everyone easily catches all of the droplets? This would fix most of the PF SS farming maps on ctb I think. What about the possibility where the map has few/no droplets and is still difficult to FC (maybe these https://osu.ppy.sh/p/beatmap?b=119021&m=2, https://osu.ppy.sh/p/beatmap?b=92780&m=2)? Would that still punish a player too much if they FC but miss a droplet? Not sure if I'm misinterpreting your formula, if it accounts for this that would be great (I suck at math can anyone offer feedback also...)

Not sure if I'm misinterpreting your formula, if it accounts for this that would be great (I suck at math can anyone offer feedback also...)This formula just assumes there's a Maximum Droplet PP Contribution, which I called MaxPP. As for how is it calculated, I have no idea but, as I said in my post, it could be a percentage of the "accuracy" (considering this is something similar to tp!standard, with "Aim", "Speed" and "Accuracy")-Kurisu- wrote:

Nope. My formula would asign MaxPP to all those PF SS. It would, however, be more fair with non SS scores: ppv1 gave a lot of PP to those SS and missing one or more droplets meant you got almost no pp. This formula gives pp almost to all players.-Kurisu- wrote:

If a maps has no droplets, then there should be no droplet pp contribution, as simple as that. As for any other case, the PP you get is strongly dependant on how do you compare with others players. For example, if there was a map with 1 droplet and you finished it missing that droplet, you could get 99 pp in the best case. If, in fact, everybody has missed that droplet, you'll get 99 pp ( 99*(1-0)^0.1 ). But if some players did catch that droplet, the pp you'd get will be punished by how many players did better than you. If only 10% of the players catched it, you'd get 97 pp (out of 100); if half the players catched it, you'd get 92 pp; if 90% of the players catched it (meaning you did really bad), you'd get 78 pp. So, the punishment is not that much.-Kurisu- wrote:

Actually, I think it should be punished more, so I'll think a little bit more about this later.
Sorry for double post, but I made this intentionally, as I felt this deserves its own post
Update on the Formula
As I found the punishment for droplet misses wasn't enough, I thought of a new way to make it harsher. Also, I thought of a way to make it related to the total ammount of droplets in the maps (it's not the same to miss 1 out of 5 droplets than missing 1 out of 100). So, here's the notation I'll use:
MaxPP = Maximum Droplet pp Contribution
TopPP = Maximum pp posible for each class of players (based on droplet misses)
PP = Actual pp given to a class
AF = Acumulated Frequency of all groups with less droplet misses
DF = Diminishing Factor (where 0 < DF < 1)
LL = Lower Limit, percentage of pp a player missing all droplets will get (a number between 0 and 1), based only on droplet misses. It can't be 0.
TD = Total Droplets, the number of droplets of the map.
x = Number of droplet misses
1] Calculate the TopPP for each class using the following formula:
TopPP = floor(MaxPP*exp(x*ln(LL)/TD))
2] Calculate PP given using the diminishing formula based on AF:
PP = floor(TopPP*(1-AF)^DF)
So, now I'll work 4 different examples to show how this formula behaves. Two cases will have TD = 3 droplets and two will have TD = 7 droplets. Also, one map will be harder to SS than the other. They also assume LL = 0.5 and DF = 0.5
Case A: 3 Droplets total
For these maps, the TopPP for each class are:
TopPP_A = floor(100*exp(0*ln(0.5)/3)) = 100
TopPP_B = floor(100*exp(1*ln(0.5)/3)) = 79
TopPP_C = floor(100*exp(2*ln(0.5)/3)) = 62
TopPP_D = floor(100*exp(3*ln(0.5)/3)) = 50
Example A-1: Easy Map
For this distribution, the actual PP given for each class are:
PP_A = floor(100*(1-0)^0.5) = 100
PP_B = floor(79*(1-0.3)^0.5) = 66
PP_C = floor(62*(1-0.7)^0.5) = 33
PP_D = floor(50*(1-0.9)^0.5) = 15
Example A-2: Hard Map
For this distribution, the actual PP given for each class are:
PP_A = floor(100*(1-0)^0.5) = 100
PP_B = floor(79*(1-0.05)^0.5) = 76
PP_C = floor(62*(1-0.2)^0.5) = 55
PP_D = floor(50*(1-0.9)^0.5) = 15
Case B: 7 Droplets total
For these maps, the TopPP for each class are:
TopPP_A = floor(100*exp(0*ln(0.5)/7)) = 100
TopPP_B = floor(100*exp(1*ln(0.5)/7)) = 90
TopPP_C = floor(100*exp(2*ln(0.5)/7)) = 82
TopPP_D = floor(100*exp(3*ln(0.5)/7)) = 74
TopPP_E = floor(100*exp(4*ln(0.5)/7)) = 67
TopPP_F = floor(100*exp(5*ln(0.5)/7)) = 60
TopPP_G = floor(100*exp(6*ln(0.5)/7)) = 55
TopPP_H = floor(100*exp(7*ln(0.5)/7)) = 50
Example B-1: Easy Map
For this distribution, the actual PP given for each class are:
PP_A = floor(100*(1-0)^0.5) = 100
PP_B = floor(90*(1-0.3)^0.5) = 75

PP_F = floor(60*(1-0.8)^0.5) = 26
PP_G = floor(55*(1-0.9)^0.5) = 17
PP_H = floor(50*(1-0.95)^0.5) = 11

PP_A = floor(100*(1-0)^0.5) = 100
PP_B = floor(90*(1-0.05)^0.5) = 87
PP_C = floor(82*(1-0.1)^0.5) = 77
PP_D = floor(74*(1-0.2)^0.5) = 66
PP_E = floor(67*(1-0.4)^0.5) = 51
PP_F = floor(60*(1-0.7)^0.5) = 32
PP_G = floor(55*(1-0.85)^0.5) = 21
PP_H = floor(50*(1-0.95)^0.5) = 11

* In my opinion, this formula works well. Anyway, LL and DF can be adjusted.

So, now I'll work 4 different examples to show how this formula behaves. Two cases will have TD = 3 droplets and two will have TD = 7 droplets. Also, one map will be harder to SS than the other. They also assume LL = 0.5 and DF = 0.5
Case A: 3 Droplets total
For these maps, the TopPP for each class are:
TopPP_A = floor(100*exp(0*ln(0.5)/3)) = 100
TopPP_B = floor(100*exp(1*ln(0.5)/3)) = 79
TopPP_C = floor(100*exp(2*ln(0.5)/3)) = 62
TopPP_D = floor(100*exp(3*ln(0.5)/3)) = 50
Example A-1: Easy Map
Group Class Users' frequency Droplet Misses
D 10% 3
C 20% 2
B 40% 1
A 30% 0
For this distribution, the actual PP given for each class are:
PP_A = floor(100*(1-0)^0.5) = 100
PP_B = floor(79*(1-0.3)^0.5) = 66
PP_C = floor(62*(1-0.7)^0.5) = 33
PP_D = floor(50*(1-0.9)^0.5) = 15

PP_B = floor(79*(1-0.05)^0.5) = 76
PP_C = floor(62*(1-0.2)^0.5) = 55
PP_D = floor(50*(1-0.9)^0.5) = 15
Case B: 7 Droplets total
For these maps, the TopPP for each class are:
TopPP_A = floor(100*exp(0*ln(0.5)/7)) = 100
TopPP_B = floor(100*exp(1*ln(0.5)/7)) = 90
TopPP_C = floor(100*exp(2*ln(0.5)/7)) = 82
TopPP_D = floor(100*exp(3*ln(0.5)/7)) = 74
TopPP_E = floor(100*exp(4*ln(0.5)/7)) = 67
TopPP_F = floor(100*exp(5*ln(0.5)/7)) = 60
TopPP_G = floor(100*exp(6*ln(0.5)/7)) = 55

* In my opinion, this formula works well. Anyway, LL and DF can be adjusted.

Too much math for me, but it seems like there's way too harsh a penalty for droplet misses, you should really fix that as it seems like it won't be much better than ppv1...
The penalty is harsh, but that formula isn't meant to apply to overall pp. If the system is going to work like tp, there should be some factors measuring beatmap difficulty (like "Aim", "Speed" and "Accuracy" in Standard) and then droplets could represent a % of, say, accuracy pp.Zak wrote:

isn't that near impossible to think about as it would take up to much time? to get the factors measuring a beatmap difficulty which i assume is done mostly by hand picking maps wouldn't really be that much of a viable option for some maps considering for some players some maps are harder than others, and getting a maplist like that for the "hardest maps" that require the most amount of skill would definitely require a intense amount of work the people working on pp for not only the ctb game mode but also the taiko and mania game mode too as all of those would also need their own high skill tier mapsets.ZiRoX wrote:

How tp works for standard: http://osutp.net/info, the difficulty is calculated by an algorithm.Amir wrote:

Tell me why a droplet miss needs to be punished harshly? Have you every tried a really hard map with Hidden where the SV went up and the horizontal sliders were really hard to SS? This kind of change is not really has effect at Standard since most good players can handle it easily, but in CtB the map difficulty is a bit lower tho catching droplet sometimes really hard even w/o mod. And in CtB one droplet is only count 10 point step asside from the max combo since it has no effect on it. That 10 point really worth that kind of punishment? Some players can miss a droplet but their spinner skills covering it and get more point than some SS record. Why they need to get fewer pp?
I think you still need to work on that formula since its aren't actualy countthe player's skill. Just how good their accuracy was.

Because especially with mods getting an SS is hard on some maps, so it should be rewarded. There are a lot maps where it is harder to get an SS than a good spin, just saying.Kurokami wrote:

Yes, it needs to be rewarded but just if the map is hard enough. But its impossible to a Ai to determine how hard is a map truly. Yes, maybe there are 30 player with 1 droplet miss and 1 with SS but that can mean two thing. First is, maybe the hard it too hard to SS so that player with SS needs to be rewarded more. Second, those 30 player just sucked and can't get that droplet because of the lack of skill but with time 50 more SS it so they slowly get fewer pp since the map is easy. BUT here comes the skill, what will happen if this is the first Insane fc for one of those players? He/she really need to get the same amount as the rest or maybe more since this is the first higher level fc? I don't think so. But then complain will happen since why he/she got more pp then the rest, etc. So in the end no system will be fair enough to all player no matter what is the formula but one pp drop should be punished too hard. Of course it can be stacked up as the misses growing and maybe add some extra punishment in it, like:Tenshichan wrote:

1 dp miss = -2 pp
2 dp miss = -4,5pp
3 dp miss = -7pp
etc
And maybe that "extra" point can be removed if this is the player is new at that level.
Well this is just a small example, but I think this can be fair enough to all players. I hope its clear enough since I'm kinda tired today. orz
I think the difficulty of the map isn't relevant when it comes to SS or no SS. For example this map: *click*. It is easy to FC even with HD DT, but it is damn hard to get an SS on, as you can see, no one has it actually with HD DT or HD HR. So if someone does the only SS with HD DT, he will automatically get more pp from it than someone who has maybe catched 15 bananas more, because it is obviously way harder to do the SS rank here than getting a good spin.Kurokami wrote:
Yes, it needs to be rewarded but just if the map is hard enough.
I agree, thats why it should be clearly checked how many players SS'd a certain difficulty with this set of mods. So if there are only 4 of 25 players with SS you will still get a decent bonus for SS. Simple.Kurokami wrote:
But its impossible to a Ai to determine how hard is a map truly.
When there will be 50 players with SS, then SS should clearly not be relevant, but only with the same mod usage that is. For example, we have a mapset, where #1-#4 are HD DT records and the rest are all Hidden SS. If for example #3 managed to do a HD DT SS, he should get a small reward for it, even though there are many SS records with only Hidden mod, so that he maybe gets the same pp amount out of it as #1 with no SS.Kurokami wrote:

I don't get it. If a newer player gets a Hidden SS on a hard map, he will certainly get more pp out of it than someone who can do it with ease. Why should a #100 player complain that a #2500 player got more pp for an SS than him. It is obvious that he would get more pp out of it because of his rank, and slowly decreased that amount when he climbs up the ranks.Kurokami wrote:

Edit: Zirox formula is actually pretty solid. The only problem I see there is to implement it.

I think instead of being punished for missing droplets, you should get small bonuses for really nice accuracy on certain maps. Take this for example, there isn't a single HD SS so if someone ends up doing it they should receive a bonus for being able to. Now i'm not saying people should get large bonuses or anything but I think maybe getting a extra few pp as a bonus for doing better than most is better than punishing everyone who misses droplets.
A Hidden SS is the maximum amount of "droplet pp" you can gain from a Hidden FC on a map. If you miss a droplet, you will only get a certain percentage of that amount. Still, this "droplet pp" needs to be weighted with the spins and the number of SS ranks with the selected (difficulty increasing) mod(s). So if you FC a hard map with SS, while only 5 other people have SS with the same mod, you will get a certain "bonus". This can be counted on every map, while hard maps automatically give you this kind of "bonus". If you miss a droplet on a map with no Hidden SS, you will still get good pp out of it, but not the maximum "droplet pp".Zak wrote:

Have you read my posts completely? It's not meant to apply to overall pp. Think of it as a bonus that decreases with droplet misses. Also, Zak's POV (increasing bonus for better accuracy) can work well. Also, I said there are some values that are just a random try. I made this (http://puu.sh/6SdOh) for you to play. If you think it's too harsh, try using a higher LL value and/or a lower DF value. Also, you can see how a bigger number of droplets makes the thing less harsh (change TD for this) and how the most influential part is how you did compared to other players (changing AF)Kurokami wrote:

Then let's keep with ppv1, where the pp was based on the rank you got on the map.Kurokami wrote:

It's just an idea about how to handle a specific part of CTB.Kurokami wrote:

Okay, I read them once again. And yeah my sentences were a bit bad. I wanted to mean no-mod SS and Hidden S. So how do you want to make difference between? Since they are almost the same but not really since sometimes "easier" to get SS than an fc with hidden. Well they are mostly special cases but still they are kinda at the same level (not counting FL). So I just want to know if you think they should be rewarded equaly or not. But yes at the end the reward for good accuracy instead of a punish for DP miss sounds much better. Of course I agree with the punishment too, since its not really that hard to get SS, I just don't think it should be high (a few pp which can stack is a good amount).
They can be rewarded equally. And again, I repeat, my formula is based on a lot of assumptions. One really important point is how to determine MaxPP. Obviously, some maps are harder to SS and the reward for SSing them should be higher and so, MaxPP should be higher. Considering how tp works for standard, if there was something related to Accuracy, one could set MaxPP to be a percentage of this "Accuracy Difficulty Value". As tp re-calculates these values for mod plays, a HD play will have a higher value of Accuracy and MaxPP would be higher for a play with HD. So it is possible for a no-mod SS and a Hidden S to be equally (or similarly) rewared.Kurokami wrote:

Okay, thats enough for me. The rest was in your post anyways. If this will be implemented than finally I can get my first place back in my country. *.*
The main problem since CtB doesn't have accuracy it will be hard to implement something like this since it needs to be somewhat different than the rest of the modes. I wonder if peppy can do it. o.o

What was a huge flaw in the PP system was shared top ranks with HD, that would reward you with tons of pp. SS shouldn't be worth as much as it was before. Just my thoughts on it.

Just dropping in to say that a map shouldn't be unreasonably difficult to award pp. It needs to still allow pp for players of all skill levels and not only the ones who can play with hardrock.
Also adding too much of a weight for catching droplets in hidden could potentially make playing for pp not fun, because it is sometimes according to luck whether or not you catch droplets if you're not a pro player with hidden enabled. It wont be good if pp will become dependent on catching all the droplets.

Didn't really wanted to post here, but some posts here are missleading or not clear, so about modifiers in CtB:
In CtB modifiers are greatly related to approach rate and a bit to circle size, I'll describe how most players use them here (keep in mind that each player is different and I'm trying to get a general overview of how mods are used in most maps)
- Hidden:
I don't know enough about Half Time and Easy modes. Only thing I can say here is that EZ+HD on hard maps are really challenging and should maybe work the same way of the other modifiers.
My thoughts about accuarcy in CtB: This is just a % of completion of the map, nothing related to the other game mode. Droplets are easy to miss and they don't even have hitsounds so you basically don't know when you're missing them. Any bonus or malus related to droplet misses should have a minor weight in the total calculation. However Zirox's calculation sounds good to detect on wich maps it could be more or less weighted.
Spinning well isn't given to all players and I think a fair calculation could be "more bananas = more weight in the global calculation". Being myself bad at spinning I think it's part of the CtB skills and this should be well rewarded in the global calculation.

- Hidden:
- AR<=7: HD makes the map way harder to play and should deserve a significant bonus, sadly most AR<=7 maps are easy maps (especially converted ones).
- AR=8: HD start to be less annoying on most maps. It still deserve a significant bonus on hardest AR=8 maps but at this point a huge amount of players can easily play AR=8 maps with HD.
- AR=9: Most players will use HD on AR=9 maps cause it doesn't disturb them anymore, some players says that it actually help them to have HD in AR=9 maps. Most of those plays doesn't deserve any bonuses, however some AR=9 maps using complicated stream patterns would still be awarded by a bonus (the idea here is that HD on AR=9 helps a bit for huge jumps and make precise patterns like streams a bit more difficult)
- AR>=10: I think only 10-20 players in the world plays AR>=10 without HD. A HUGE amount of players will say that it's easier to play AR>=10 with HD. I don't think any bonuses should be deserved for most of those HD plays (Actually a malus would fit better but I think it's a bad idea since it will screw the map rankings)
- Most of FL plays are done in AR=8 mainly on stream maps. I don't know this mode well enough to say more about it.
- AR<7: HR would deserve a little bonus depending on the map difficulty.
- AR=7: HR start to have a huge effect on many players, clearly deserve a bonus but nothing really huge since most of those maps are pretty easy.
- AR>=8: Everything over this point should deserve a nice bonus depending on the map difficulty.
- AR<=7: DT would deserve a little bonus depending on the map difficulty.
- AR=8: Here is the most complicated part. AR=8 maps with many 1/2-1/4 movements and/or really huge jumps and hyperdashes are most likely being harder with DT than with HR. However most AR=8 maps are still easier with DT than HR due to how they're mapped.
- AR=9: I actually don't know any AR=9 map being easier with HR than DT, those FC are rare, even clearing AR=9 maps with DT is challenging for most players. The FC's should get a significant reward since it shows the player capability of reading high speed AR, memorization and ryuuta control.
- AR>9: I don't know any player capable of reading this speed.

I use hidden, because it removes some of the clutter from the screen. I have trained myself to stare at the top half of the screen instead of the bottom half. It allows me to react quicker. It isn't by any means a cure all solution for all fast maps. I think this part is determined by skill level. When we can read the notes faster, then we can tackle faster patterns. When the patterns reach your skill boundary then hidden becomes much harder.
I prefer to play maps that I don't need to develop muscle memory to complete. I want to be able to follow the note path and respond to it as I go along. It is the maps that I cannot do this that are very difficult for me. Since hidden makes it more difficult to learn patterns of a map beyond a certain level and playing without hidden reduces my accuracy to hit patterns, I am left without any good options on how to learn this map. These are the maps that I expect pp from.
Even if we can say that the average person is capable of playing a map with hidden, the average person may not prefer to play a map with hidden. I would hate it if I worked hard to play a difficult map, and get nothing for it even though not many people have played that map with hidden or other mods. I mean I don't care if I don't get the pp of someone who uses the other mods which are more difficult, but I think I deserve something for placing relatively well compared to my peers in a hard map.

"1.5 direction with converts" seems to actually work the best imo. But hard to say, there's so many maps.
Also some maps seems to get overrated on all versions, like "Can't Defeat Airman [Holy Shit! It's Airman!!]" and "Kokou no Sousei [Collab]".
Also some maps seems to get overrated on all versions, like "Can't Defeat Airman [Holy Shit! It's Airman!!]" and "Kokou no Sousei [Collab]".
I have major issues with this. Big Black and Kokou no sousei are not even close to being equal in difficulty. The difference between 360 BPM and 240 BPM is huge. Big black is also AR 10 and Kokou no sousei maps (Chaos and Collab) are AR 9. Jump intensity is also a huge factor.
This issue affects both models.
I can't beat Chaos. Someone else could evaluate that difficulty and have a more accurate opinion .

First of all, simply taking the BPM does not work well. The big black mostly has 1/1 and 1/2 notes while kokou no sousei mostly consists of 1/2 and 1/4 notes, essentially making it closer to 480 BPM if you want to directly compare it to the big black.
Secondly AR is not factored into the difficulty algorithm. It will play a big role when computing pp, but it is not considered for beatmap difficulty / star rating.
My last point is, that the scoreboards indicate, that kokou no sousei is not very much easier than the big black.
The "Collab" diff of kokou no sousei definitely is a lot easier than the big black and should not be on par. It has a few hard parts but is mostly easy. Will look into that one.
IMO Big Black is still harder because it's AR10 instead of AR 9, and the patterns seem slightly easier. The only way it could be worth more is if you account that Kokou no Sousei is about 2 times longer.Tom94 wrote:

I'm by no means a good CtB player, so I can't really give feedback on the current difficulty ranking, but I'd be interested in seeing your alogrithm's opinions on these two maps:
https://osu.ppy.sh/p/beatmap?b=25580&m=2
https://osu.ppy.sh/p/beatmap?b=93893&m=2
Both of these use a special kind of pattern that is extremely hard to play but doesn't rely on big or fast jumps, so I think your difficulty calculation method might possibly underrate these?

Yeah, it is the same in standard. Mainly because it doesn't really connect well with something like "aim" or "speed". Secondly there are many varying opinions - some people saying AR10 would be easier than 9 and others telling me the opposite.VelperK wrote:

It is factored in for pp calculations, so don't worry about that part.
Yes, they're hard.Luna wrote:

Catch The Beat calculation methods
Catch The Beat is different in multiple ways, by how jumps work and how streams work, mostly. Playing on a 2D plane is a lot diffrent from standard osu!, along with the predefined movement speeds of the catcher. Thus, skill based calculations based on the limitations of Ryuuta among other things must be taken in account for.
There are some main factors which determine how difficult a map is for Catch The Beat:
Map Settings This goes back to the basics.
- Approach rate: This should be documented in difficulty by the actual drop rate of the fruits. This also gives AR10 the much needed skill requirement it actually calls for.
- Fruit Size: This is pretty obvious. The smaller the fruits, the harder they are to catch accurately. Skill requirement is based on the field in which you can actually catch the fruit, rather than the size itself.
- Overall Difficulty: I don't know how this is handled in the map, but as far as I know it only affects the HP loss when missing. I don't think that applies too much to skill, but for players who can just barely pass a song, this would come into play.
- HP Drain Rate: Same as above, only comes into play for those barely making a map.
Beat Placement Factors based on the placement of sliders and circles themselves
- Movement: How much the catcher needs to move to catch the fruits. In stream maps like Marisa Stole the Precious Thing, this would become classified as less difficult since you don't have to click and simply inch the catcher, where in the system used for standard, it would be classified as difficult otherwise.
- Jumpiness: This is the general distance between beats, based on how fast the catcher must move. This also applied to sliders and their slider ticks. This also heightens more based on the general theta of jumps in a row (especially hyperdashes in a row) What I mean by theta of jumps in a row, as in a map with periodic jumps is probably more difficult than one with one part of it having multiple in a row (This sort of compares and contrasts between kinds of jumps and what kind of skill and perseverance is required to acquire a good score) Also, generally, faster hyperdashes are harder to chain off of, e.g. Can't Defeat Airman!.
- Speed: This is how fast the catcher needs to move around in succession. This would rate maps like val0108's Talent Shredder or With A Dance Number as high skill examples for this sector, mainly because of how fast the catcher needs to switch one direction to another and how fast of fingers the player needs.
- Long jumps: Originally pixel jumps, these are jumps that are enough for the catcher to reach with the new hyperdash system, but still require precision placement to catch, as well as timing. An example can be seen in Wild Eyes [JAMES DIFFICULTY!!!] As it has long but viable jumps.
Mode Specifics and Other Stuff
- Mode Specific Maps: Don't need to be buffed. They are probably already difficult as it is with the algorithm that's in place. Plus, it was set this way to entice players to play those maps. This pp system focuses on the player's skill, and tries to measure the skill needed for each beatmap, so making bonuses of that sort is incorrect to ranking..
- Fruits before and after spinners: The time before spinners and after spinners doesn't need to be checked because of how bananas aren't necessary to a full combo.
- Accuracy: In general, accuracy is easier to come by in Catch The Beat, and as such, changes may be made accordingly.
what kind of proof do i have to provide to refute this argument?Tom94 wrote:
Referring to the "Chaos" diff:TheVileOne wrote:
I have major issues with this. Big Black and Kokou no sousei are not even close to being equal in difficulty. The difference between 360 BPM and 240 BPM is huge. Big black is also AR 10 and Kokou no sousei maps (Chaos and Collab) are AR 9. Jump intensity is also a huge factor.
This issue affects both models.
I can't beat Chaos. Someone else could evaluate that difficulty and have a more accurate opinion .
First of all, simply taking the BPM does not work well. The big black mostly has 1/1 and 1/2 notes while kokou no sousei mostly consists of 1/2 and 1/4 notes, essentially making it closer to 480 BPM if you want to directly compare it to the big black.
Secondly AR is not factored into the difficulty algorithm. It will play a big role when computing pp, but it is not considered for beatmap difficulty / star rating.
My last point is, that the scoreboards indicate, that kokou no sousei is not very much easier than the big black.
The "Collab" diff of kokou no sousei definitely is a lot easier than the big black and should not be on par. It has a few hard parts but is mostly easy. Will look into that one.
Both are pretty difficult. The extra AR makes it more difficult for me, but I guess it could be seen as easier or harder depending on how well trained your eyes are at reading fast scroll speeds. AR 9 gives you more time (might be a placebo effect) to read the objects. Sometimes it is the case that if you need to read the objects as they are scrolling, you are already taking too much time to hit them correctly.
There are more red fruit jumps in Chaos and it is the longer map, which makes it easier to make a mistake over the course of the run. I'm not sure how the pros consider red fruits in terms of difficulty compared to awkward patterns. Some awkward patterns are more frame perfect than 99% of red fruit jumps.
Do you value hyperdash jumps as more difficult than large jumps that are not hyperdashed? Hypers can be very easy, even the very far ones. They get more difficult when you have to chain them. 1/4th hypers tend to be more precise than 1/2th.

There are need to be more change.
Only so few maps are big pp maps. Standard of giving pp is too much towards on few factors. Accordingly, if we just played the pp maps, we can farming many pp even though not FCed or cleared with Easy mods (EZ, HT, NF). If you want, i can post the examples of the maps too! It is worst than ppv1...

why does non FC map appear on top ranks?
Also for normal diff with HR, and FL (1 miss)

best performance is marked base on your stability and "performance", thought some maps is still not FC-able / Hard to FC, like Rainbow Dash or Kirby mix Deluxe.

Yes, because AR10 is 1.5x faster than AR9, and AR9 is 1.5x faster than AR8, and etc-Ryuujii- wrote:

so, technically, since you have that less reaction time, AR10 is excessively difficult, much like how much more difficult CS10 is than CS9, and to CS8, and etc.
It's just all game elements that don't appear to make a huge impact, but they really do when you get it to the highest difficulty of these effects.
FC shouldn't have to matter too much (Although, it does give a tiny boost) It's more based on score and accuracy than anything now, mostly because of the fact that the only thing that slowly increases when you get better is the accuracy itself.

FC only mattered because often FC means getting good rankings. It's more of "This is the difficulty, how much of the difficulty can you do?" And that's pretty much how pp goes.
It no longer focuses on other players. It tallies up how well YOU do, then compares that tally to others.

You can't farm the hard pp maps without close-to-fc scores, let alone with easy mods. It would be nice if you could provide examples of where such things are possible.-PM- wrote:

to reply onto the farming case, there are some songs that indeed give a lot of pp with little effort from above average players:
https://osu.ppy.sh/b/161980?m=2 is one case, getting top 200 nets you quite a lot of pp, even when you're at 4.6k pp.
https://osu.ppy.sh/b/55474?m=2 is another example, the intro may be annoying, but its a straight shot to 300 combo, I see why it would give pp because the spacing between the jumps are huge and its pure hypers, but like I said any above average player can easily get accustomed to those jumps and either fc, or even miss once near the end and nets you still some good pp.
https://osu.ppy.sh/b/84485?m=2 the jumps may be annoying but it is definitely doable, only thing I found hard on this is some jump at 369, like I said it gives a lot of pp as well.
although these songs were me experimenting to get under rank 100 with not so much effort, I did in fact move a lot of ranks so far from a few maps. And I'm considering these songs farmable since like I said above average players can do, or fc the songs that I listed with few retries
it does seem massively spaced maps gives a lot of pp too which may be concerning, since some of the maps have a few spots that are considered hard to pass, but require a few attempts to actually get used to it and pass massively large spaced notes.

There was a bug that rated some maps too high. Glee Cast - Friday is one of them, which will get fixed today. Can't say anything definite about the other 2, but the difficulty algorithm will get some adjustments either way.Minky wrote:

New PP, new farming maps.Seph wrote:
Well you really can't change the fact that this version of pp still counts map hoarding though.
there will always be maps picked out if you are good enough to farm them, pp can't be changed to a point of progression, ranking is ranking, no way around it i guess, there will always be shortcuts and tricks of the trade.
you should focuse more on AR10 when you play with HR, and AR9 maps with DT have to be rated higher
I have this growing concern that the CTB pros are going to keep complaining about every remotely non-crazy maps giving pp until the only way you can get pp in maps is to FC hyper filled songs that only the top percentiles can play. I agree that it should require effort to be rewarding, but grinding isn't fun. It doesn't show that you're skillful. It only shows that you've played a song enough time to complete it without missing.
This isn't about hard maps giving pp, it's the fact that they should be giving MORE than the not so easy maps, instead of around the same or even less, in ppv1 after getting into around the top 200 getting a good score on a hard map would give nothing unless you get top 20 or so (and sometimes not even then), and that's why ppv2 needs to make maps like that more rewarding.
A nice is example is Kokou no Sousei, in ppv1 rank 4 gave me 0pp but then if I wanted i could go get top 5 on maps that aren't very difficult and I would probably get pp.
None of us are saying that easier end maps shouldn't give pp at all, we're just saying that harder maps need to start giving more so things are somewhat balanced.

I've been looking around top 50 player's profiles and I see that most of their top performances are basically No mod and HD records. DT, HR, and FL records doesn't seem to have an effect on PP which concerns me. I mean sure the top 5 might have one or two HR records but the vast majority doesn't have theirs shown on their top. Could be a bug?
P.S- Compiling a list of hard maps for CTB would be really helpful to determine which maps should give more than others.

Only if the pro guy literally has one good score and only shit others... which is very unlikely. Believe me, outweighting good plays with worse ones is ridiculously hard in this system, unless map weighting is malfunctioning for easier maps.Seph wrote:
A player who focuses on heavily weighted maps can still be outranked by a player who has played more not-so-hard maps than him.
Like, 50 regular maps > 1 super hard map when it comes to pp gain
I don't really like the list all that much as pretty much everything near the top is unranked, most of those maps I've never even played and I'm not sure just how many people have either to be able to compare difficulty, seeing more of the harder ranked maps would help compare as it's more likely people will know what those play like to be able to compare them properly. It would probably be a good idea to get some higher skilled players who have a pretty good grasp on what makes the maps difficult and have them help out on figuring out a good way to calculate difficulty.
