The rating system

For each match an "expected" score is calculated from the rating difference of the two players (if the ratings are equal, the expected score is 0.5).

This expected score is then compared to the actual score of the game (1 for win, 0 for loss, or can be anything in-between for multiple ends).

If the expected score for the player was higher than the real score, the rating drops, if the score is higher than the expected score, the rating is raised.



Formulae:

Where We is the expected score, and dr is the difference in ratings before the match.

The rating change is calculated from the following:

Where W is the score of the event, We is the expected score, n is the sum of the scores by both players.


The system is based on the rating system developed by Prof. Árpád Élő.

What does ≈ mean in front of the rating?

The ≈ sign means that you have played less than 20 games, therefore your rating is "provisional". The sign will go away after the 20th game.

Ratings are calculated differently if you play against such players. The rating adjustment will be less.

If your opponent has never played a game before (denoted by ---) the rating change will be half of the normal. If your opponent played only 10 games, the rating change will be 3/4 of the normal, if your opponent has played 20 games already, rating change will be normal as described here.
