Rankings & Ratings
Rankings and ratings lists
Rankings and ratings are calculated in the same way. New Zealand ratings calculations are based on a system similar to the United States. A player’s rating depends on the number of wins gained against the opponents played in a tournament, compared to expected wins based on the differential in rating between the player and his/her opponents. A fuller explanation is given here.
The rankings list includes all players who have played 40 or more rated games in the previous 2 years.
The numerical and alphabetical ratings lists include all players who have played in at least one rated tournament in the previous 2 years. If a player returns after a 2 or more year absence, the previous rating from the All Ratings list is applied unless agreed between the tournament organiser and the player.
