Elo Ratings per Match since January 2013

Choose a table: Match scores, player Elo ratings, player rankings.

A player's elo rating is considered provisional (P) until they have either completed six matches or played matches at at least three different tournaments.

The probability of winning is equal to the predicted share of points scored. A player rated 200 above another corresponds to a 76% chance of winning.

The K value is a development coefficient, and it reduces large swings in the ratings of established players. The K value reduces over time, similar to 538's elo ratings for tennis players: 250/((player's match count+15)**(0.4)))-10
