Talk:Elo rating system/@comment-24.251.44.132-20111013002853

Just an FYI. The fundamental theory behind Elo's rating system has changed. They no longer assume a normal distribution, but a logistic distribution. Not much different overall, just has a finite support over the ratings; versus the normal distribution, which has a very small yet positive chance of a rating being either negative or infinitely large. I doubt this matters, since most people reading this don't care about the theory....
