Hello, are sliderbreaks counted when calculating pp? Because i got a -1 run (with 2? sliderbreaks) on this map http://osu.ppy.sh/b/285549 with 98.5%, and I expected that play to be worth more than nothing..
dat information tho.Full Tablet wrote:
Is the length bonus factor, when calculating the accuracy pp of a play, independent from the accuracy percentage?
For SS, the expected probability of hitting each hit correctly tends to 100% (perfection) when increasing the amount of circles
[expected in the sense that the (probability of hitting each circle correctly) makes it so the (probability of getting a rate of correctly hit circles equal or higher than the rate of correctly hit circles in the score calculated) is equal to a predetermined probability],
while for 95% rate of 300s, the probability tends to be only 95% (and the value comes closer to 95% more quickly than in the SS case).
Because of that, accuracy-wise, there isn't much difference between getting 96%acc in 200 circles and 300 circles, while the difference is more notable between a SS in 200 circles and 300 circles.
As a way to quantify the difference, here is a set of graphs comparing how much the Expected Unstable Rate changes when changing the amount of circles (with a formula based on the expected unstable rate formula I showed months ago, but this time accounting for the probability of getting 50's and MISSES; this new formula shows similar values with high accuracy, but more accurate values with low accuracy, the downside is that it takes a ridiculous amount of time to calculate: calculating only 140 points for the graphs took about 1 hour). Here is a sample of the 2 formulas in a graph varying accuracy with the other variables constant: http://i.imgur.com/6LdrKIg.png (The one with the lower values on low accuracy is the new formula).
All the graphs are calculated with OD10 (changing the OD doesn't make much difference in the graphs with high accuracy, since with high accuracy the prevalent hit window is the one for 300s, so changing from OD7 to OD10 just roughly halves the expected unstable rate).
In the X axis is the amount of circles, and in the Y axis is (Expected UR with 100 circles) / (Expected UR with X circles) (that way the influence of accuracy alone and OD is discarded from the graph). That way, a Y value of "2" means half the expected unstable rate compared to 100 circles.
The 2 sets have the following difference:
The first set sets the (probability of getting the accuracy inputted in the formula, or more) with the (expected UR calculated) to 50% (that way, the accuracy corresponds to the median accuracy with only 1 try).
The second set tries to model the amount of expected retries a map would get based on the amount of circles: A map with 100 circles would be retried 108 times, with 200 circles half that amount, etc... (this assumes the player has the patience to play each map only a set amount of time, and that the amount of circles is directly proportional to the time each retry takes) This way maps that are more likely to get "fluke" accuracies caused by a lot of retries would give less (for example, a player who only has the skill needed to get 90% chance of hitting a 300 would eventually get a SS in a map with 30 circles if he retries a lot of times, but that would be practically impossible if the map has over 100 circles). If a map is replayed 50 times all with the same Unstable Rate, then the (probability of getting the accuracy inputted in the formula, or more) with the (expected UR calculated) is equal to 1/(1+50) (this corresponds to the formula of the expected value of the lowest value obtained in a perfect die with infinite sides with values that range from 0 to 1). I know this is not the best way to model the amount of retries, but it is something.
First Set:

Blue: Graph for SS.
Purple: Graph for 99%acc
Brown: Graph for 95%acc
Green: Graph for 85%acc (95% and 85% graph lines overlap each other since they have very similar values)
As you can see, in the SS case, the amount of circles has a bigger impact compared to the other cases with lower accuracy. Also, the point where increasing the amount of circles doesn't change significantly the expected unstable rate anymore is set farther to the right of the X axis when the accuracy increases. For any accuracy inferior to 100%, there is an horizontal asymptote of the graphs, but for 100%accuracy, the Y value goes to infinity (since, with an infinite amount of circles, the expected UR to get 100%accuracy is 0).
For high accuracy on circles (Acc > 0.7, so the hit window of the 300 judgment is predominant), the value of the asymptote for the expected unstable rate is approximately:(The asymptote is the same both for the cases with only 1 retry and several expected retries).

I see what you mean, they are difficult in their own ways, do you really think unlimitation is nearly as hard as sousei? Sousei has no fc's (apart from you know who) and unlimitation has multiple HDHR scores, lol. I think there are very little players that would actually find unlimitation harder despite having a higher star rating.GoldenWolf wrote:

Damn ponies and their pp. It seems as though shorter maps have way too much emphasis on accuracy, considering how easy it is to retry them until you get a better percentage.silmarilen wrote:

almost half of the pp from the map i linked comes from accuracy, purely because it's od8+dt, there are other sub 300combo maps that give similar acc score, boosting them up by tons when they arent actually hard mapsGoldenWolf wrote:
accuracy points is calculated on the number of circles of a map and how high the OD is, it has nothing to do with the actual length of the map
Other examples of this are https://osu.ppy.sh/b/27737&m=0 and https://osu.ppy.sh/s/155691m, a lot of the difficulty is reading which the current system doesn't recognize at the moment. Tom said that he's still working on creating a satisfying algorithm for maps like these.Zare wrote:
http://osu.ppy.sh/b/227061
This map and similar ones are extremely underrated by the current system because what's the main challenge of the map is reading. I mean, the top 50 isn't even all FC (granted that's because of the 1/6 at the end but still).
Is there any chance of this getting improved at some point?

I know this may be kinda selfish to ask, but can someone put this on the wiki? I'm not 100% sure of where to put it. I was thinking about this and the only way to find it was to go back quite a bit of pages. This piece of info can be interesting to some players.Tom94 wrote:
I forgot to mention this on the wiki-page:
Every score gives a small base pp amount of 0.25, decreasing by a bit with every new highscore that you make. With 1000 highscores you get around 200pp and with 5000 around 400pp. The cap is 416.666pp at the moment, assuming infinitely many highscores are possible.
(pp gain = 0.25 * sum 0.9994^i, i=0 to amount of highscores)
This gets less and less relevant the higher your pp goes and is meant to both encourage playing more maps for the lower-level players and prevent big rank losses after making a new score at the lower ranks.
In the mid-high ranks it is pretty much irrelevant, since 99% of the people have enough highscores to be less than 50pp away from the cap.
I'll just quickly do the math for you to show you just how inefficient that kind of "farming" would be:tfg50 wrote:
And also, that small base pp can amount to way too many ranks. In my case, I need to click 18 times to show all my scores on my page and you have 50 scores showing when you first open it + 50 more from each click. That means I have 900-950 scores. If i just played easy/normal maps until I got closer to the cap I would jump from rank 2757 to 2050 or lower as of right now (something between 235 and 242 pp). I feel like this kind of jump is too huge, maybe you could put a hard cap on a lower amount of scores.
Because the only hard part about them is the length.iderekmc wrote:
why do these 0108 songs give so little PP like only 160 more or less if only a few people can fc with 1 mod..? i think they should give like 250 or something lol

I don't know any maps where you actually have to spin very fast to complete them with the exception of a Demetori song and that AugoEidEs song (dumb super long spinners). Also, losing your cursor during a spinner really only affects mouse users because of cursor drift, tablet users can use their muscle memory to hit the note with no issue. I may be wrong on this part, but isn't it against the mapping rules to put a note too soon after the spinner?TheVileOne wrote:
I am curious if there is any plans to give a spin bonus at all. There are several maps where spinning fast is more important than accuracy and these performances should be awarded something. The faster you spin the harder it is to find you cursor when you come out of the spin. There is also the cases where there are notes very closely after the spinner which would make getting bonuses more risky.
Would anyone disagree that spinning fast is a skill and should be rewarded as such?
What about unstable rates? I've seen people get SS's on maps with 120 unstable rates, and others SS with 70. Should the player with the 70 unstable rate be awarded more pp? They both did what was required of the map and achieved the SS, but one player did better and was not rewarded for it.TheVileOne wrote:
It would be a minor bonus. I don't think it would hardly affect the map's overall rating in comparison with other maps. Consider scores where the only difference between them is the spinner bonus points. I think people that can spin faster should be given more points. They got a higher score with same accuracy/ mods. Their play should be considered more highly performed. It would also counteract small changes in accuracy due to the player getting a better score from a spinner bonus. For the sake of accuracy it must be counted.
Just because peppy felt that spinners should have score bonus doesn't mean they should be given pp also. Unless unstable rates are accounted for I cannot agree that spinners should be given a bonus. In my opinion, a lower unstable rate play is much better than a higher scoring song because of a spinner bonus.TheVileOne wrote:
In a perfect world I would agree that would be considered as well. But in reality pp must be consider for the OD of a map. Also unstable rate doesn't affect score. Obviously peppy felt spinners deserved to have bonuses. Taiko doesn't allow you to get a bonus off the spinners. CTB should certainly deserve a small bonus as well.
There are many maps with tied mod combinations that only differ due to spinner bonus. We should be differentiating each tied play, because some people can get bonuses many thousands more than other players, especially on longer spinners where endurance is concerned. Why should a deserved number 1 play on a map not be considered the best performance compared to the several dozen other people who got less points?

That means that people passed your rank and when you beat one of your personal bests your rank updates. If you spend 30 seconds looking on the other threads about ranking you can find that answer. You don't even need to use the seach thingy.Honza wrote:
I have one question. How can I get bigger rank after I've improved my old record? I mean yes if the map is easy I shouldn't get anything but how can I get worse by improving my plays?
No one cares about spinning. It's really a shitty skill and it shouldn't be rewarded much, any random crap player can outspin a lot of top players if they try.TheVileOne wrote:
It should be given pp because of several reasons.
1. It's a skill, and an integrated part of playing. There is no argument that can be made that will make me believe otherwise that someone spinning at 470 SPM is performing equally well to someone spinning at 300 SPM.
2. It affects score. A player with a higher score due to something that requires skill should be awarded something even if that something is very marginal. I don't see this value being very high, at least for sane spinning SPMs. If someone averages near what osu! can get for a max spin, then a point given per spinner is reasonable. Given that 1 mod added gives more than that, it would work out. (Obviously the value would change based on length of spinner).
3. At the rate most players spin the bonus would probably be less than 1 pp per spinner and close to nothing near the SPM considered easy to obtain given the OD.
4. Makes beating a score with a better spin rewarding.
5. Gives more points to Incognito, one of the best spinners in osu! Check this map. Adding HardRock isn't enough to take the number one spot. There are people in top 50 who get more points than four mod plays. Spinning ability is certainly more impressive in this map than playing it with all mods.
6. Removes point ceiling on maps. An SS can be worth more points with a better spin.
afaik, ppv2 rates how hard it is to FC a map, not to pass it, so I don't think HP drain is consideredTheVileOne wrote:
Is drain even considered at all?
Plz, #8 disagrees.TheVileOne wrote:
If you need a certain level of spinning to pass a map that map isn't worth playing. Noone should play maps with high drain because they are good at spinning. That will be a reward not taken by pretty much any player.

A person who spins very hard will be more likely to combo break than someone who doesn't. It takes more stamina to take a number 1 rank than it does to just SS in a map where there is an SS all mods. The difference needs to be considered, because just the fact that mods were played is not enough to correctly calculate performance.This is pure rubbish right there. Why should it be considered? Because you tried hard spinners and got a bit more sweaty? People still do it even when #1 doesn't matter in PP. As I said, they are #1 (or just the best with given mods) and it's enough of a reward. I'd even say it's exactly what people do want when they engage in a spinner war. It's for sure not a way of saying "I'm better".
Hi. I'm a person who spins 450+. I doubt it takes much more energy than a lazy spin.TheVileOne wrote:
I think the reason why pro players aren't great spinners is because they conserve their stamina for the streams and other sections of the maps. If there was a pro that was a great spinner and a great streamer and could apply both to a map, then that would be a much more impressive performance than one who did the same thing but barely exerted any effort to complete the spin.
If we had more pro players capable of challenging rrty or cookiezi scores, then I think spinning would become much more important to the pro community, because it actually matters. Why should pros care about spinning if the score they get is determined by the number of 100s in the song rather than how fast they spin? I think a lot of pros treat spinners like break time and a map will instantly become more demanding if they were required to actually exert effort during these periods.
The real question here is how much more energy does a vigorous spin take compare to a non-vigorous spin. How much further can a pro stream by not vigorously spinning? Some pros I question whether they even know of to spin to begin with. I've seen them spin so slow that they get a 100 on the spinner. Is it some sort of contest to see how slow one can spin among the pro community?
Some maps, such as the 0108 maps, rely on reading and difficult patterns. The current system can't rate how difficult patterns are or how hard a map is to read due to some limitations, so the end result is that those maps are undervalued. There are also some other issues with the system, but that is probably the one that is causing the lower star rating for most maps. Tom would like to add that into the rating system but he can't at the moment, whenever he can he will.- D a s z x - wrote:
i think some maps are harder but the star diff for that is lower, why
If it's much easier to do it that way... why not just do it then? You're clearly either making things harder for yourself, or just don't spin enough. Seriously, even if it's something completely useless, you will improve if you practice. People just don't work on spinners as much, so most stay within the 350-450 range because that's enough to pass OD10 spinners. If you're missing the note afterwards, just remember where the note is and start moving there a bit earlier. It's really not as hard as you make it sound.TheVileOne wrote:
There's only so many times I can play https://osu.ppy.sh/s/25 before I need to rest and I'm not even spinning nearly as fast as some spinners. Spinning harder does affect my aim afterwards, because I am a mouse user and my hand gets tense after a fast spin. I could spin more slowly and my hand would not tense up. Stamina certainly becomes an issue on really long spinners.
Also notes close after the spinner make it more risky to spin faster. It's much easier to spin like an average spinner than to go into a tight circle around the center like tablet players do or flying around the corners like mouse players do.
There's what Mathsma said, and there are also maps that are a bit overrated (Koigokoro), but nothing can be perfect. The system is usually pretty darn accurate.- D a s z x - wrote:

You know damn well that finding a good balance between not making mods useless without giving them too much reward is a rather complex and subjective solution. Even so, what I meant in that post was aimed more-so towards the notion of being able to disregard your score so that you don't lose PP, or something along those lines. The servers can only store your top score because of the way the system works and has always worked, so Tom94 can only work with that saved score.TheVileOne wrote:

Mod for at least HardRock and DoubleTime will likely never be adjusted manually. That is, because they are literally treated equally to nomod scores, just with the mods' effects applied.TheVileOne wrote:

I would say that there's a limit to how much accuracy one should lose though. If you're getting double digit 100s then obviously this will affect your pp count greatly. There is no preventing a terrible performance with an added mod overwriting a good performance.

If this is supposed to be an indication of skill then there's no reason to assume a player got worse for having his/her score overwritten with one of lower pp value...
If new pp value is smaller than current pp value for some map, don't change the pp. That's one line of code. Seems like common sense to me to make it work that way.
Only data you need is pp obtained and pp for the same map for the same player which looks like it's stored on server.
Maybe there can be a disconnect between pp given for a map and top score saved but that doesn't really matter.

At the very least low cs is overrated.
People who say this are very careless. In some environments it's overrated but in others it's severely underrated. Large jump maps can rewards up to 500pp while far faster maps can barely top 300pp. It really depends on the map, jumps formed from dt tend to be easier to follow which is why people would call dt an overrated mod while short fast streams and smaller faster jumps are rarely ever mentioned because they don't fit the "overrated" trend. It seems the problem is that balanced maps are underrated rather than extreme maps overrated, a map which is extremely fast and mildly jumpy seems to be penalized far too much for not having long streams or immense jumps despite maintaining huge difficulty throughout (I'm looking at maps DT'ed by dragonhuman and co.).Yales wrote:
