How it works

LaZerRanks is an idea I came up with about a year ago when I realized just how poorly the WCA average and single rankings represent actual competition performances at any given competition. Inspired by ELO ratings, I decided to make a system that would accuratley represent a person's expected time at a competition. The system I came up with uses user inputed parameters to take a weighted mean of a person's solve times in an inputed interval of time (my standard interval is 365 days). Although I believe that my standard interval of 365 days is the best, It's fun to play around with the parameters and see how it affects the ratings. My hope is that if a better system exists, this interface will allow the user to determine it. The formula for LaZerRating is simple. Every solve time is multiplied the inverse of the days elapsed since that solve was recorded. The sum of the weighted solve times in the interval is then divided by the sum of the inverses of the days elapsed of the solve times in the interval.

rating = Σweighted times/Σweights

The LaZerRanks All-Time Records

This is a list of the top 20 3x3 Ratings ever in any time interval of 365 days as of April 5th, 2018.

The LaZerRanks Today

This is a list of the current top 50 3x3 Ratings using a time interval of 365 days as of April 5th, 2018. The ultimate goal of LaZerRanks is to allow for user interactivity with the program, allowing users to generate infinitely many rankings. For now, as I work on developing this interface, here is the current state of LaZerRanks.
