How Ratings are Calculated

We use the Elo system to calculate each player’s new rating after each tournament. 

Starting Off

Each player starts at a rating of 800. This number is a measure of relative “skill” between each other players.

Changes in Rating – How Ratings are Calculated

The system essentially compares the actual result of the game with a predicted result and awards/takes more points the further away from the prediction, the result. The predicted result is calculated by comparing the two players’ current ratings. A player whose rating is 100 points higher than another is expected to win 64% of the time, while a player whose rating is 800 points higher is expected to win 99.9% of the time.
