What we are afraid of is that those badly converted maps will actually weight more than how difficult they really are, because of settings, usually with high density but easier than a taiko specific with less density, etc...

By the way, did you have time to work on an improved algorithm ? Or do you have an estimation about the time needed for it to be finalized ?

I have a prototype running locally and will post results with various settings as soon as they're ready. Those steps are there exactly to ensure, that converted maps will _not_ be overrated. ;)

I'm all for giving things a try, but my concerns will still be there until the results are visible. Let's see what you can pull off Tom.

I believe in Tom :D
He did impressive work for the standard ranking and lifted it to the next level worth calling ppv2.

i'm curious about how well it'll work for the really good players that don't have great scores/don't play often or whatever

actually i'd like to know how the current broken temporary system is but we're not allowed to see sadface

Ehh...
I guess the new pp system should scan the players' brain for skill that he didn't put into a high score? ;)

Players will still have to get great scores. The metric is called "performance points", not "potential points".
Also the current broken algorithm simply does the following:
  1. Multiply accuracy with star rating of the map (up to a maximum of 500)
  2. Divide result by 3 if converted
  3. Build the diminishing sum of the best scores for every player


That also makes it pretty obvious why it's not working well, heh? Still better than nothing - that's why it exists for now.

There should be a way to convert maps better than it does at the moment and still keep the combo score ratio the same.
Streams might be the biggest obstacle but I believe it is possible. :<

ideally hell yea

i mean the players that don't specifically have a lot of scores but still have some that are really good blah blah you know what i mean

quality vs quantity how will it play out overall

I have got a question.
If x had 10K PP
and y had 3KPP
Let us assume that y got better score than x on the score board, does that affect the PP or just the rank position or none?

You are still thinking inside the box, namely that of the old system.

ppv2 has a beatmap difficulty algorithm, meaning this is what needs to be worked out precisely to get accurate results. Your performance is a statistical analysis compared with a perfect performance on the map. Player ranks in comparison to each other on a single map should be irrelevant. That was the problem with the old system for many reasons.

I'm sure there will be a LOT of testing. When tp first came about, it wasn't anything like it is now, and Tom tweaked it a lot, even adding a new variable (aim). I'm not predicting it's initial failure for taiko, but there is only room for improvement upon the algorithm, even if the first results may be completely off.

I've got some initial difficulty lists to show off here:
https://docs.google.com/spreadsheet/ccc ... 0VGc#gid=1

This spreadsheet does not contain every single beatmap, only the ones I selected for testing. Please give me feedback and let me know which version of the algorithm works the best. ;)
Nashmun
Hum, for me it seems like the basic algorithm is the most accurate.

The others one still have some weird results like Freedom Dive's oni > Inner oni while it's the contrary or still a duckling > I'm your daddy Fatal oni which is the opposite aswell.

I still need to look at it more closely though.
BrokenArrow
Yeah, same goes for HIT AND RUN IN 1920 A.D. and NNRT (which should be placed a lot lower normally)
But from first look things don't seem to be very far off, well done so far

With colour changes w/o converts:



sacrifice and chipscape taikosakis are easier than who's your daddy or akasha, also gothic system is much harder than taikosakis not just a little :?


This is a lengthy post but please bear with me~


Some of these are human some of these are inhuman and some of these are easy, I wanna see what your programm thinks of these maps :3c

Hey, could you include those maps into the difficulty rating ? They have lower bpm but they are actually pretty hard compared to regular 220+ maps, so it would give us a good indication on how you balanced technical vs speed :)

most of the maps listed i've never played because of wtfbpm and me being slowface so i'd like to know this

otherwise goodbye to my rank i'll see you all in hell

Added another algorithm version, considering rhythm changes, to the end. Will add more versions when I get back home.

I think the pattern difficulty needs to be improved quite a bit - right now chipscape and Broken the Moon have the same rating (45). I could FC chipscape if I actually tried (and I'm really not very good at high BPM), but I'm not even able to pass Broken the Moon.
Even with problems like that, it looks SO much better than what we're used to having, so good job.
