Would be nice if the PP system changed to score instead of rank, so a high S can yield more points than a normal SS. :D



I strongly oppose the implementation of mods into the ranking system. First of all, there is a max score for a reason, as the max score of 1,000,000 gives you a good idea of how far you are from perfection. Second of all, mods aren't worth any points right now, meaning that the implementation of mods into the rank system would lead to a HUGE fluctuation in some players's rank. Ignoring the mode specific mods such as SpinOut or FadeIn, the current mods still don't fit into the mania gameplay at all. Mania has the most flexible mode, with the greatest amount of variations, and there is simply NO need in implementing mods to spice up the ranking system.

Specific reasons why each mod is pointless:

HardRock
First part of HR: There is no point in decreasing the hitbox of the notes, as unlike the other 3 modes which are either 300/100/0, mania offers so many different possible scores (MAX, 300, 200, 100, 50, 0). HR is a thing in other modes because the max score is easily attainable, yet for most mania maps, 1,000,000 is quite a hard task.
Second part of HR: What are you going to do, increase the scroll speed? The scroll speed has 0 influence on the score and the game, as everyone can change the speed to something that they feel comfortable with. If HR increased scroll speed, we could simply slow the scroll down manually.

FadeIn/Hidden
FadeIn/Hidden would have been a decent mod for ranking, as unlike HR, players cannot manipulate the visual strain it adds. However, the idea that the hidden part increases after each successive note (until around 70%) is simply retarded (I really can't find another word), as the variation in how much of the screen is hidden makes the mod easily manipulable.

DoubleTime/NightCore
DESTROYS THE SONG. Jokes aside, a big part of DT is about the increase in visual strain, as the notes speed increase as well. Same argument for HR. DT is still barely viable just because of how you have to click the notes quicker now.

Besides score, Combo is very important to determine players' skilll in hard chart. Although the combo system in o!m is fluctuated (Ex. Those who get #1 got less combo than others), some patern allows only high skilled players to FC, and the score system does little impact on that.

See this shit? Niclijou is this high when he is always using these key mods! This was today, and the whole time he had 4k on. This is why the key mods should be unranked.

HR is unranked, yet it only changes the accuracy for notes.
RD is unranked, but even though it changes the note placements, it still will let you end with the same combo number of the song.
And yet, Key Mods are ranked, even though they change the whole songs track and combo number!

Some people are saying "But some good songs are low key counts." YES I KNOW! I play those songs too and not always 7k! I just want the mod unranked, not the lower key songs!

Take this into consideration people, it's totally unfair for all of us skilled players.

I didn't even know key mods were ranked. What the hell?! That is a load of crap. That shouldn't be ranked at all.

Well keymods don't work on mania specific maps. So it won't be a problem if..... on second thought, let's not bring that up right now.

Also I completely disagree with who ever said combo is important.This isn't standard, a play with high acc and 2 misses, one at 1/3 and 2/3, is much more impressive then someone who missed 5 notes at the end of the song. Miss count is pretty much included in accuracy, making combo the most useless and broken score calculating utility.

Also, why is everyone talking about mods? No one ever said that they'd be considered in ppv2, this is greatly off topic. We should be contributing on what makes a map hard and what makes a map easy, with possible example, to help tom make his algorithm.

That rank is from the old & broken PP system, from farming easy maps that are low key by default - key mods have nothing to do with this.

If you're seriously complaining about someone using a mod combination in multi for fun that gives them a maximum score cap of 200,000 then wut.

This!

Imo, this topic should get cleaned until Tom can get his first algorithm out so we can give proper feedback. At the moment without a base, all we can really do is indicate which patterns are tricky, rather than actually help improve it

@Drace, I'm specifically talking about key mods, not trying toget other mods up.

Also, I bring up combo because it's a simpler amount of notes reference.

@Cozzzy, If the old system were the case, wouldn't those players still be low? Wouldn't we all be back to the ppv1 placements? Also, EZ and NF don't affect pp given (Same pp reduction is applied), I was trying to point out key mods -_-

Mania rankings on the site still redirect here https://osu.ppy.sh/news/73929298672 so idk why the broken preview-rankings still show up in-game, but we're basically still using the old PPv1 system with even more bias towards easy accuracy scores at the moment, but that'll get fixed. My point was that in that player's example, he didn't use key mods for his rank at all, but just played easy songs.

Honestly, I just don't like it when people imply that anyone who doesn't play 7K exclusively is not a "skilled player". Without the key mod, I'd have to play the slow LN-spam maps people keep making for 4K :(

First, I did not imply that only skilled players should only use 7k. I mentioned that in my first picture post. I play other key songs, just only if the max diff isn't 7k.

Second, LN-spam maps? Those are mania specific, and shouldn't change keys when you want it. Also, LN are a huge thing in o2jam, and that's the closest reference to this game. Some people can make good LN maps, then some people are just plain shit.

And finally, if he played easy songs, he should be as low as the pit of earth from pp.
Key mods are a mania only thing. No other modes have any mod specifically for their purpose of changing the notes, and because of that, the new system currently ignores that mod and gives all pp to a max diff key mod play.

Are auto converts a big deal in rankings? Admittedly this evidence is anecdotal and I don't know what ranking system the ingame system is displaying, but when I was solely playing auto converts I was just inside the 10k mark, ever since I've been playing osu!mania specific maps my ranking has shot up to 3k. I haven't suddenly become a much better player, but I've suddenly overtaken seven thousand people.

If you mean that you've become #3k or so during the last 3 or 4 weeks it's normal, lots of people have seen their rank skyrockets.

Anyways, to answer your question (I'll try to make it short since it has already been discussed for a dozen pages now), autoconverts aren't good enough (quality, gameplay-wise) to reflect what actual mania (-> maps made specifically for mania) provides. Just read through the entire thread to see arguments as to why we should keep or remove them from the ranking system.

The topic atm is helping Tom defining what a easy/hard map is for his algorithm.

What if we had something like a MMTT? (Mania Map Testing Team)

Since most mania maps have their multiple difficulties and some being harder than the highest star rating in there (ex. Wotamin-Gigantic O.T.N. Entozer's Another > L.I.A.'s Insane difficulty wise), the team would test a map before it is qualified or approved and they send in their difficulty ratings? I think this would help with the mania specific maps a lot.

It would indeed work, but as Tom suggested, we should leave Tom his chance at making an algorithm to see if it works. Hopefully (and surely) it will work better than ppv1 :p

We have discussed this earlier in the thread (page 7), but Tom wants to try create an algorithm first. It would be easier it there was an algorithm, but a team dedicated to judging the difficulties of maps would also be very accurate.

Good luck with an algorithm, but mania is probably one of the hardest modes to accurately calculate with a single unchanging formula, as there is simply too many variations possible with long notes and short notes in 7 keys.

MMTT would be a perfect (if not essential) way of accurately calculating a map's actual difficulty. The current star rankings aren't doing that much, and self imposed difficulty names such as [ADV, EXH, INF], [EZ, NM, HD, MX, EX, SC, SHD] or arbitrary levels such as XXX's Lvl 36 can often vary between one mapper and another. There are so many maps that are far beyond the max star rating (examples include SHD maps such as Ende, Mephisto, Shuffle Heaven, Big Money, Days of Dash or straight-up hard maps such as Imperishable Night 2006, or Sweet Rain [Another (somehow mapped tagged as "Normal" difficulty]).

And just out of curiosity, will there be a temporary ranking released any time soon?

Hello everyone,

note that currently the osu!mania ranking is not functional. If you have any suggestions on how the future system should work, then leave it in this thread, please. :)


I'd like to mention a few things regarding how I plan on tackling this.

The general direction:

  1. First of all, everyone can decide on his/her own which maps he deems good or bad, or which ones he/she prefers playing. We shouldn't be forcing certain maps on people by making them worth more for no sensible reason.
  2. I'll try to make an algorithm that's fair for both auto-converts and mode-specific maps. We will all see how it turns out, and if it's alright, then I see no reason to reduce the value of auto-converts. As mentioned above you are still free to play the maps you prefer playing. I can however understand where the auto-convert argument is coming from, and it'll definitely be addressed if there won't be a good solution that weights all maps the same.
  3. Default X-key modes exist for each specific beatmap for a reason. My initial plan is to give slightly more points to the default X-key mode of a particular beatmap than any custom one. This is not set in stone yet and most likely will change in one way or another while testing.
  4. Unfortunately X-key specific ranking is not going to happen. That'd be for one part a way too huge amount of things to manage and for the other would clutter up everything.

Beatmap difficulty:

This is were you all can help the most. My current concept is somewhere along the following: Similarly to how tp works with osu! standard maps I would like to instroduce strain values to measure how hard it is to play a certain map. This essentially means, that a higher note density will also be considered harder, while the algorithm is aware, that using a single hand or finger multiple times in a row is more demanding than simply alternating.
For mods the map will simply be transformed accordingly to what standard does in the moment. HR will increase OD, DT the speed at which the map plays back, etc.
I have not yet gone in-depth and it would be great if you could give me hints of what the hardest patterns are and how to rate difficulty. Any X-key feedback is welcome!

If it counts in auto converts it should has something in it about the sliders. In osu standard maps the circle to slider rate is often 1:2 or so for sliders and this goes pretty bad in mania. Even if it is an autoconvert you are playing it way relaxing with those high amount of sliders. If you pay attention to it while playing an autoconvert you will notice that most of the time your hands are resting and your inputs are actually very slow and there is not much you are actually doing, even if the song sounds super fast or difficult or so. You can play extremely fast songs that are difficult in standard mode alot easier. example: https://osu.ppy.sh/s/38316. That song is 250 bpm but most of the time what you are doing, is just holding down the sliders which isnt hard and prepare for the occassional burst of notes and then go back to holding sliders. Who is afraid of the big black is also a good example of how auto convert can turn a very difficult beatmap to something so simple.
Most older beatmaps, or beatmaps with fewer slider count translate into more diffcult beatmaps. If there are few sliders the autoconvert will create more notes and you have to "play more" compared to a autoconvert with alot of sliders.
Examples:

Those autoconverts convert into maps with alot of notes
https://osu.ppy.sh/s/43960 Extra diff
https://osu.ppy.sh/b/103281 Collab diff
https://osu.ppy.sh/b/125102 Another diff
http://osu.ppy.sh/b/152561 Extra diff

Also no idea if this is related but auto convert also likes to scramble the notes for streams under 160 bpm or so all over your keys and from 160~200ish bpm streams will often turn out as a simple staircase. On even higher bpms i think auto convert starts scrambling it again. Well not sure about the actual BPM numbers there but its just - lower BPM, scrambled streams - hgher BPM staircase. I think one find the other easier but i think a simple left right motion is easier to play than multiple notes at many different keys

Are you arguing to change the way autoconverts are generated? They'll be bad no matter how they're converted. The extra dimension of having to aim with the cursor is lost when converting to mania so it's essentially trying to expand a 1 key game into a 4-7 key game and it simply doesn't work well.

In case I missed the point entirely: the ranking algorithm should already into account the low strain and note density of slider maps so they shouldn't be worth much anyway.

As for Taiko and CtB I also got an initial list for osu!mania ready now. This is the gamemode I am the least sure about my results and so far only the base algorithm is done with no variations. However, you can already see how low converts are weighted simply because they are so easy, I've included a few of the harder ones:

Some quick feedback on things I'm seeing right off the bat. I'm seeing a lot more lower key maps being put at a higher difficulty than higher key maps, even though they're quite a bit easier.
ex. Akasha's 8k FEVER is lower than Little Star 4k INF.
unfinished's 4k Accel is 8 higher than its 7k Burst.

Another issue is how you're handling the difficulty for long notes (or maybe HP Drain/OD). Wintersun 7k Winter is definitely a lot lower than it should be.

Lower key maps should be worth a lot less now. Also there was a bug with holds that made them considered pretty much not at all. This has been fixed, too.

For science, please add these autoconverts to the sample pool for the algorithm:

Map-specific feedback/pointers from initial checkthrough:

polygon [SHD] - Underrated. Jacks inside chords/LN patterns.
Gigantic O.T.N [Entozer's Another] - Underrated. dunno why.
Gigantic O.T.N [L i a's Mania] - Overrated. citation needed. I know this map is much harder to play well than it is to play mediocrely.
G59 [Level 36] - Underrated. citation needed.
Nou Shou Sakuretsu Girl [Hard] - Underrated. that ending...
Zoetrope (TV Size) [RC's 8K SC] - Not sure if underrated or I just suck at 8K
Hesitation Snow (Short Ver.) [8K Another] - definitely underrated but I also suck at 8K
Wintersun (Bobby D'Ambrosio Mix) [7K Winter] - underrated...? citation needed. density+LNstreams
Insane Techniques [5K Black Another] - underrated, has hard jacks in the end
Maware! Setsugekka (TV Size) [PROGUY's 6K MX] - underrated.
Crack traxxxx [4K EXH] - overrated
VALLIS-NERIA [LeiN-'s EXH] - overrated
Akasha [8K Hard] - underrated. even with me not being all that good in 7K+1 this map deserves way more than it gets.
Senretsu no ryu [Hard] - overrated

-

Overall after the hotfix this algorithm is already starting to look real nice. Jacks needs to be handled better, other than this there's some unclear factors that would need tuning.

I looked at the document and it looked pretty accurate overall (I can't tell for harder maps), but I found something which I find weird.

For the song Igorrr - Unpleasant Sonata, the Insane converted map is considered the same level as [Shi-Ra]'s Hell [SC] mania chart. I played the Insane chart in case it was really as hard as the mania chart and it was very easy to pass compared to Shi-Ra's one, which contains a couple of hard LN parts (maybe not that hard but at least ten times as hard as those in the converted map) and has a very fast ending wich can be failed if you get out of sync too much.

I'm not an expert for judging maps but I'm convinced that if converted maps are worth less than real mania charts, the Insane converted map should not be considered the same level as the hardest mania difficulty.

I did not search for other examples and I have no idea what might cause this unless chords are worth many points, because there are much more (but not many) chords in the converted map than in the mania chart.

Apart from that, I'm very pleased to see some good progress and I can't wait for a new pp system to be implemented :)

Passing autoconverts is always easier than passing mania charts due to the nature of drain setting difference between the two modes and the way it transitions on the autoconvert. You should compare how hard are those maps to play correctly and not to spam through and pass (ask yourself how hard would it be for you to S it).

  1. croix (roxas mx) underrated, it starts getting quite fast near the end which makes it slightly harder and makes me lose a bunch of acc.
  2. crack traxxxx 7k inf overrated, everything on this map is just on a different level than the ones you put around this level.
  3. game brain (lunatic) underrated, everything on this map is just on a different level than the ones you put around this level.
  4. wintersun (bobby dambrosio) strongly underrated, long notes are really punishing + slowjam makes it slightly harder.
  5. piano concerto no.1 (lvl 31) overrated, everything on this map is just on a different level than the ones you put around this level.
  6. G59 (lvl 36) underrated, everything on this map is just on a different level than the ones you put around this level.
  7. Gigantic O.T.N (Lia's Mania) overrated, It has same density than the diff by entozer, but this map uses more chords and minibreaks which make it require less speed, stamina and acc. On top of that, there's a lot of symmetrical patterns which make it slightly easier as well.
  8. chain destruction (siilento remix) overrated, I lose a bunch of acc on the end, but it's not enough to be that highly diff judged.
  9. smoooooch 7K SC overrated, only reason it's hard is because of the SVs which are memorizable. Should be ignored.
  10. rhythmical planet (collab) overrated, there are some pretty hard parts in there, but also quite a bit easy parts that pump up accuracy so it doesn't deserve to be so highly diff judged.
  11. imperishable night 2006 (7k insane) overrated, there are some pretty hard parts in there, but also quite a bit easy parts that pump up accuracy so it doesn't deserve to be so highly diff judged.
I judge underrated/overrated based on how hard it is to get a good score, not on a clear basis.

can't judge any of the higher diffs. can't judge any of the lower diffs. Also can't judge half the maps since I didn't play them yet. (I mostly play BMS/o2jam convs)
What I can tell is that the system seems to be non-linear.
I mean maps around 20-30 seem to be far more spread out in skill level than 40-50.
It also seems to be inconsistent, it doesn't follow a smooth exponential curve since some lower levels seem to be closer together again.
This might be irrelevant, and it might not be, you'll know that better than me. I'm just saying.

It's quite a bit rough around the edges but it doesn't seem too bad for a first try though. Good job so far ^^

On a side note: you could use aqo's 'osu!mania maps sorted by difficulity' thread as well. I don't know about the lower diffs, but the lvl 7-11 maps are sorted pretty well, I'd say it has about a 1 level error margin. do note that there is a huge gap between 11 and 12 though.

- Levels are different too much.



- 153 is easier than 151,152 too much,shouldn't put here.



- 167 is harder than 166 too much.

Just a quick glance >,<
Clearly there is huge issue about low key amount diff earning a relative high difficulty. One thing I want to point out is that you cannot simply put them all under one single rating system although we have to do that in the future anyway. So now in the early stage of ppv2 I suggest make unique list for every key amount or at least don't put something completely different(for instant 8k and 4k) together. The comparison among different key amount are totally none sense for now.

A couple of opinions:

In difficulty 6, take a look at 7k charts.
Unfinished 7k Hard and Eden HD. Those two clearly don't belong the group of difficulty 6.
Eden HD -> although there is no really outstanding difficult part in this chart, parts contain continuously 1/4 in a relatively high BPM and many 4key-press at the same time make this chart extremely hard compare to other maps in the same level.
Unfinished 7k Hard -> 146BPM with some 1/4 and easy 1/2... seems not harder than other maps in this level. Actually not. Pattern make this chart a little bit hard to read and press for players in that level such as 00:20:065 - and 00:25:099 - , and for those who can not master higher level it is extremely hard to earn FC and high acc(OD8 btw).
So what's important? Sharing a similar average density, songs contain remarkable hard part (like burst or strange pattern) are usually deserved a higher difficulty. Everything unique may makes a chart harder than usual.

That is a problem. hard charts with lower average difficulties usually result in good score and OK acc, but actually to master them you need to enter a much higher level in order to manage those extreme hard part. This cause many underrated cases in the list and we need to pay more attention on the maximum difficulty of a chart to judge its rate.
Same thing also happened in 4k. Eg: Wu Xuan Lan 4k Hard and Insane Techniques 4k Hyper


Speed change and large amounts of LNs makes difficulty rise. We're so Happy obviously easier than other two charts due to this reason.
LNs patterns and speed change should also be considered.

Good Job!

Just out of curiosity, why does the system count the easier map as my highest PP yielding map?


From my userpage, it says the 4K map is my one of my highest maps when in fact, I did a lot better in a higher difficulty.


Is there a reason for this? Am I mistaken for saying that each beatmap only accounts for the score with the highest difficulty? (Well even if thats the case, shouldn't the 7k map be ranked as a higher PP map for me?

EDIT: Does this mean that ranked accuracy also takes into account converted beatmaps and beatmaps of lower difficulties?

The current pp system is not functional. Please read the opening post next time.

I've been to this page at least 30 times and I've read the opening post quite a few times.

When you said the pp system was not functional I thought you meant that the PP calculations were not altered yet, not that the percentage accuracy was not functional. My bad anyways.

First of all, wow this list is looking pretty nice. Goob job Tom!

Here are a couple of inconsistencies I found

41 - Passionate 7k SHD - https://osu.ppy.sh/b/312638
Underrated, the layered long notes and the sv change is much harder for this level
36 - Freedom Dive 7k SHD - https://osu.ppy.sh/b/208353
Underrated, this is very very hard overall.
44 - Shining collection, Erox's Shining time - https://osu.ppy.sh/b/296010
Slightly overrated imo, not many layered long notes or any of the crazier patterns.
25 - Ascension to Heaven (LV. 44) - https://osu.ppy.sh/b/279472
Quite overrated, this has raining notes but no layered long notes, is much easier than long note overlap heavy songs
123 - Days of Dash Shi-Ra x Rumi SHD - https://osu.ppy.sh/b/326507
To me, very underrated. Long notes are hard.

These are a few that aren't listed by the others that I believe that are slightly off. Thanks for the read!

What you said about Ascension to Heaven and Days of Dash is pretty subjective, I know a few people having a harder time with density maps than with LNs heavy maps.

Hello everyone,

note that currently the osu!mania ranking is not functional. If you have any suggestions on how the future system should work, then leave it in this thread, please. :)


I'd like to mention a few things regarding how I plan on tackling this.

The general direction:

  1. First of all, everyone can decide on his/her own which maps he deems good or bad, or which ones he/she prefers playing. We shouldn't be forcing certain maps on people by making them worth more for no sensible reason.
  2. I'll try to make an algorithm that's fair for both auto-converts and mode-specific maps. We will all see how it turns out, and if it's alright, then I see no reason to reduce the value of auto-converts. As mentioned above you are still free to play the maps you prefer playing. I can however understand where the auto-convert argument is coming from, and it'll definitely be addressed if there won't be a good solution that weights all maps the same.
  3. Default X-key modes exist for each specific beatmap for a reason. My initial plan is to give slightly more points to the default X-key mode of a particular beatmap than any custom one. This is not set in stone yet and most likely will change in one way or another while testing.
  4. Unfortunately X-key specific ranking is not going to happen. That'd be for one part a way too huge amount of things to manage and for the other would clutter up everything.

Beatmap difficulty:

As for Taiko and CtB I also got an initial difficulty list for osu!mania ready. This is the gamemode I am the least sure about my results and so far only the base algorithm is done with no variations. However, you can already see how low converts are weighted simply because they are so easy, I've included a few of the harder ones:

Get the feedback going. ;)
