well u do have to remember that the FFR Rank is compared to every other ranked player, so your rank can still lower if other people pass you up. how it works on any ranking system when put up against other players. i think what he meant by "your rank can't lower" is that you cant be put back into d4 if you made it into d5.

Your skill score can definitely drop.

Let's say your best score is 1-0-1-0 with 500 combo on Reality. It's your best score by far, but you just missed once in the middle.

Then you get an 8-3-1-4 score on Reality with 880 combo. Say you were doing well but utterly fucked up the end of the last stream. Obviously this is going to replace your old score because the combo is so much higher, but your skill score WILL drop because the PA is now trash. If you were just a few points above the D5 cutoff, this would bring your score right back down into D4 despite the fact you can obviously get 1-0-1-0 on Reality, meaning your score is now a much worse reflection of your real skill.

It's a problem with combo scoring; the tier point system had this issue too.

Yep, that is pretty much what happened to me, although thankfully it still has me placed as D5. I had 6810 skill level with that first Mirage Garden score as my #2. After getting that second score, it became my #7 score and my skill rating dropped to 6752, hence the rank drop. Too bad this is pretty much going to remain an issue until raw scoring is implemented.

I think the New Leaderboard needs some fixing.

POST # 1000! Weee

[yo man im awesome]

aka the source of FFR the Game's problems continues to be Combo Scoring

[Rapta]

Combo scoring sucks

[Kanzas]

Pfft, Combo scoring.... Who needs it?

[Guest15937]

I've said it before, but all these extra stats and rankings really are pretty meaningless until the game's biggest problem (combo scoring) is addressed

Just wondering if the system take into account users that have the same number of points. For example, shadow and Dossar have both 9,430 and should be tied for 3rd place.

Skill rating is only rounded down to the nearest whole number for display on the leaderboards so it is a more palatable number. Your skill rating is a floating-point number which can only be tied if another player has the same best scores on the same difficulty songs, or by a coincidental mathematical anomaly.

yo like where did those coefficients come from

i know you accumulated data from the tourney or whatever but.....

im just curious

[rushyrulz]

It's a combination of Zenith Score and the GOAT Tracker. With some modifications.

The coefficients came from a polynomial regression, which is a way of fitting a curve to a set of points. The points used came from some data that Prawnskunk had that is used during division placement. It's a list of score equivalencies, like a AAA on a difficulty 38 is equivalent to 13 goods on a difficulty 45 (I just picked random numbers here).This set of information was generally agreed-upon by the division placement staff, and proved to be the simplest and most accurate way of making a formula.
