Rating System
The Chess 'n Math rating system does not differ from that of the FIDE a lot in the way that the formula is derived, but the variables are different. According to their website,[1] the formula is as follows, for one tournament or multi-game event:
- Where W is the number of wins, L is the number of losses, and D is the difference in rating (your opponent's minus yours), with a cutoff value of ±350.
As it appears, the number of "expected wins" for one game is equal to the difference in rating divided by 800, plus 0.5. The cutoff value of ±350 makes the limits of these "We" values, 15/16 and 1/16 respectively. A person can also win bonus points equal to:
- for doing extremely well in a series of games. (G stands for number of games played).
As of September 1, 2007, a "bonus" of 2 is added to every game won, up to a maximum of 50 games.
