Rating

Formulas

For calculating ratings for players who previously did not have one, a provisional rating is given. This rating is given at the completion of the player's first tournament where the formula used is as follows: *Provisional Rating = (Average Tournament Player's Rating) x (Player's Result / Average Result At Tournament) For players who have previously established a rating the following formula demonstrates how a new rating is achieved. *New Rating = (Old Rating) + (KT) x (Player's Result - (Average Result x Old Rating / Average Tournament Old Rating)) KT = Tournament Coefficient (Ranging from 4 to 1 depending on strength of competition)
