What is Skill Rating?
Skill Rating is a ranking metric aimed at determining the actual skill of a player based on their performance on any song in-game.
The Skill Rating formula was designed by Trumpet63, PrawnSkunk, and Silvuh. The project has undergone numerous iterations since its inception in February 2015, and continues to evolve.
Increasing Your Level
Your Level/Skill Rating is an exponentially weighted average of your top fifteen scores. Your personal best score matters the most (24.04%), and your fifteenth best score matters the least (0.17%). Your rating for each song is determined by the “AAA equivalency” formula.
The AAA Equivalency Formula
… Or essentially, X number of goods on Y difficulty is equivalent to a perfect score on Z difficulty.
The above graph describes the relationship between AAA equivalent and raw score. However unlike the previous formula, your rating is now scaled by difficulty as well as good count. Crossing into the third dimension allows the Skill Rating formula to calculate AAA equivalent scores with greater than 28 goods, and in some cases, well over 1000 goods:
The constants used are the result of applying a learning algorithm to a set of data points accumulated by the Official Tournament division placement team and other community members.
