Final 2005/2006 Ladder Rankings

(last updated Wednesday May 17, 2006)

The club ladder tracks the playing strength of club members. Only singles games are counted. The system is similar to the ELO system used in chess, (we actually use the Glicko rating algorithm). The change in your rating will depend on how much higher (or lower) the other player is that you beat.
