Skill Rating & Leaderboards Discussion [Updated Oct 16]
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. To-Do List: Feature Requests • Levelrank breakdown page of your top 50 scores. • Make skill rating levelranks publicly searchable. • Expand scope of skill rating beyond your top 4 scores. • Distinguish inactive users from active users. • Add skill points section on results screen in R^3 for every score. Changelog February 16th, 2015 • Skill Rating and Global Leaderboards released. February 17th, 2015 • Skill Rating levelranks released. April 2nd, 2015 • Skill Rating levelranks are now publicly searchable April 3rd, 2015 • Skill Rating now includes token songs. October 1st, 2015 • Skill Rating v2 released. October 16th, 2016 • Skill Rating v3 released. • D7 cutoff raised to Lv.95 Skill Rating by Jeffrey Spreng, Max Proske, and Silvuh Ryvinia is licensed under a Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International License based on work at http://www.flashflashrevolution.com/leaderboards Last edited by PrawnSkunk; 07-5-2020 at 04:57 PM.. |

Re: Skill Rating & Leaderboards Discussion [Updated Feb 16]
Suggestion: Add a place to view top 1000 ranks if that isn't there
Edit: Found it!

Re: Skill Rating & Leaderboards Discussion [Updated Feb 16]
Good gravy there are a lot of people looking at this thread... :P
Anyways, I'm curious about something; so does the Skill Bracket mean that's your official division for tournaments and stuff? Has the skill bracket requirements changed?

It's not based on average rank anymore, just your best 4 scores.

Re: Skill Rating & Leaderboards Discussion [Updated Feb 16]
The boundaries are currently 0/2300/4700/5600/6450/7630/8650 for each respective division -- However these numbers are not final, and will change as the skill rating formula evolves over time. As I receive feedback and suggestions, I will manually adjust the cutoff for each division.

Re: Skill Rating & Leaderboards Discussion [Updated Feb 16]
I would be more impressed with the daily stats page if it kept track of how many times you had made the list
And then make a leaderboard for that too, even if it's just for the GT stat (most AAAs would just be an excite bike fest) |

Re: Skill Rating & Leaderboards Discussion [Updated Feb 16]
