Rankings & Ratings
In New Zealand, we calculate rankings and ratings the same way. We use a system similar to that of North America. A player’s rating depends on the number of wins gained against the opponents they played in a tournament, and compared with their expected wins. See a fuller explanation.
The Rankings list includes all players who have played 40 or more rated games in the previous two years.
Rating list by position, Rating list by name and All Ratings
The rating lists are for the benefit of the tournament organisers, who need to be able to apply the correct grade or seeding to entrants. The Ratings list by name (alphabetical) and Ratings list by position (numerical) include all players who have competed in at lest one tournament in the previous two years. The All Ratings list is the complete list. If a player returns after an absence of two years or more, they will have their previous rating (from the All rating list) applied.
The tournament director does have discretion to ignore the historic rating in placing a returned player. If you have any doubts about where to place or seed a player, please contact the Ratings Officer.
