Wieso wird das so gehyped der erste try ist doch oft der beste für ne bestimmte map bei vielen jedenfalls

Vielleicht bei schlechteren spielern.

Well instead of PP talk, how about star rating? I joined after the star rating system was implemented, but I know there used to not be a star rating system, and after gaining some experience, I think we would be better off without SR, as it's very often wrong and gets good maps underrated by people.

You misunderstand, star rating is the foundation of pp. You can't talk about star rating without also talking about pp.
Also there was a star rating before I implemented the current one. It sucked, since it gave any moderately hard map a maximum of 5 stars. Given how many people use the current system to sort their maps somewhat by difficulty it'd be insane to even consider removing it.

As an alternative to getting rid of the pp system, is it possible to get a toggle to just hide all pp/ranks in game?

I don't understand why they can't just be ignored. We can't add toggles for everything. I manage to ignore pp/ranks at 99.9% of the places I go, so why can't you? Heck, I haven't tried to gain pp and had a blast in osu! for the past 2 years. I find it hilarious, that during an OWC match I gained my (then) #1 pp score on a map that's not even overrated pp-wise.

So I'm guessing we're unwilling to wipe out current PP data in order to implement a better system? We need to maintain backwards compatibility (as in we can recalculate PP with what data we have). That means no usage of replay data in calculations and no adding metadata to submitted scores?

Not entirely. Completely depends on just how good a system working with full replay data would work. If someone is willing to try and to implement it properly if it's successful enough, then it might realistically happen.

Is it computationally infeasible to redesign PP to require replay data? Right now PP is basically calculated with max value of map PP with whatever mods are on as the input to a function which adjusts the PP according to max combo, number of missese, and acc right?

1. Yes, it would be computationaly feasible. We'd need to throw some more more machines at it, but it does scale. The data volume required for storing all the difficulty data and replay data would increase drastically, though, going into the terabyte range. Since we don't have replays stored for all scores this system wouldn't work for everyone, too.
2. Pretty much.

https://osu.ppy.sh/b/847257 Isn't something wrong, when this map is over 10 stars? (The mapper achieved it by spamming spinners that are so short that you get 300 on them, without spinning)

Yes, the algorithm should know this and act accordingly, but since this'll never be ranked it's not a real issue. Easy to fix should it become a priority at some point.

Can you release your map parser, i'd be willing to experiment with different PP systems if that was released. I'm too lazy to write a parser for the maps myself.

The .osu file format is simple enough that writing a parser should take an hour at most (ignoring sliders, which is fine for most maps, because their difficulty doesn't depend on them). If you are too lazy to do that (or you don't know how), then you'll also be too lazy to do a good job with pp.

I am sorry I kinda shittakled about you yesterday. But I hope you realize that I am really, really depressed because of those side affects of ppv2. To be honest, I don't care how players would think which would be better(score/ppv2) but the side effects are really bothering me.

No need to be sorry. I don't feel at all like you "shittalked" me. You merely stated your opinion (and lack of understanding as to why ppv2 is barely changing).
As to the side effects, well, don't really have anything to add to my last answer. In the end I think it's best to follow whatever maximized enjoyment for most people.

ppv2 is unquestionably more accurate than ppv1, but people overestimate how accurate it is and it's led to a bad mindset about maps among a large portion of the community.

It may have its inaccuracies when rating maps with respect to each other, but it's pretty good at rating players if both try the same maps. I don't think the player ladder is off by much when considering only the players who actually try to gain pp.

https://ask.fm/Doyak/answers/132869691162 https://ask.fm/Doyak/answers/132869972506 anything to say about this?

You know, ppv1 was based only on map popularity and the scoreboard. That's what Doyak seems to want back.
Thing is, ppv2 was not forced upon players. I originally made ppv2 as a third party website called osu!tp. An overwhelming amount of players wanted it to become official, which is the only reason it did.
Scorev2 doesn't give sliders the same accuracy requirement as hitcircles because ppv2 underweights certain types of sliders. I don't know where they pulled that from. Sliders got changed because it simply doesn't make sense for them to give free 300s. If we introduce a new scoring system which is supposed to improve upon the issues of the old one, which requires a purge of old scores, then we might as well fix as many other wrong things as we can.
Doyak also doesn't seem to realize the effort it takes to change pp. It takes many hours to just properly test a modification of the algorithm, since beatmap difficulties for all ranked maps need to be re-computed, and then pp for all players needs to be re-computed so that I can even look at how the new leaderboard would look like. Combine this with the fact, that I already spent weeks back in the osu!tp days trying to improve the difficulty calculation algorithm without being able to find satisfying solutions to the long-known issues it has. So no, I don't want to spend such a significant time in addition to my full-time occupation.
Lastly, I agree with his concern about mappers focusing on pp. I just love certain types of maps which are no longer made. I also miss the battles for #1 on the leaderboards. But in the end I still believe we should be focusing on what makes the majority of the playerbase happy. Back when only ranked score existed people complained how bad it was everywhere. ppv1 initially removed some of these complaints, but things got even worse later on. Ever since the introduction of ppv2 the amount of dissatisfaction on the forums about the ranking system has been at an all-time low.

So you're going to personally decide if someone else meets your standards and replace you? What if there is no one able to replace you and make a better system?

I feel like I can best decide that, yes. Of course the community is the one judging the overall quality of the rating system, but there are certain other properties more or less behind the scenes which are necessary to provide a robust system.
If there is nobody able to make a better system, then obviously we stay with the current system. No reason to take a step backwards. So far I provided everyone with code from tp/pp who showed interest and had some sort of proof-of-concept to show to me. Sadly that was only 2 people. Tillerino and Kert.

Is Peppy planning to ask someone else for the PP system since you don't have time ?

Who is he going to ask? Anyone who wants to improve the system or make a new one has all the tools needed. I already said multiple times, that I'd be more than happy to let someone else take over if I am happy with their approach.

Isn't the duration pp flawed, if it only takes into account the amount of notes, and the not how absurd some maps are i.e FDFD and things like that, which should give more than they do for how difficult they are to FC, let alone accurately FC.

"Duration pp" are multiplicative, not additive, so they just scale the base pp which do depend on the difficulty of the map.

Currently top 3 pp scores are about 10-20% of your total pp. Do you think they should be weighted more?

Assuming pp would perfectly rate every play so that everyone is happy, then I'd say only the very top score should count. But since that's impossible we need to incorporate multiple scores so that outliers can't falsify rankings.
Regarding how closely to the top scores are taken into consideration there isn't really a clear answer. Obviously I feel like the current amount is okay, otherwise I would have chosen a different one. I know people who'd like less and I know people who'd like more.

I don't really want to argue about Cookiezi, but i dont honestly don't think you should compare players in any kind of way. You never know how much someone is playing offline, how hard he trys or what he is acctualy able to learn. To me cookiezi definetly can't compete with Rafis and Hvick atm.

Given that there is no truly objective measure of skill I'm fine with disagreeing.

http://ask.fm/Tom94/answer/134488788686 Is that really so? A lot of people must have been destroying it. A few months ago I edited a few grammatical errors in the English. I didn't need anything special to do it. I guess the few ruined it for the many...

I didn't check the previous question's validity. I suppose everyone who wants to know whether it's editable right now can just test it. :p

Oh wow, I didn't even know. My bad, then. I'm still not the right person to contact for this, though. Never wrote anything in the wiki (aside from the shoddy original pp page).

I may have misunderstood one of your answers earlier, where you said that you have no time to manage PP and hope someone takes it over, did you mean you are giving up on it entirely, or are you just postponing it until you take care of University?

Really not sure. I'm doing a PhD, that's for certain, so I'll need at the very least 4 years until I'm through from now.
