Ratings | Rushcliffe Squash Club

This table calculates ratings of players using the Elo system as used at national level.
E.g. see en.wikipedia.org/wiki/ELO_rating_system

League positions are used to assign a start rating, then the ratings of each player are adjusted by each of their results; the end result is the ranking shown below. Exposure is the no of results used in getting from the start rating for a particular player.

Click on a player to show or hide the sequence of calculations which results in their final rating value. You can select various different parameters in the next section to control how the calculation is done.
