I’ve updated the rating estimates in the People section. In case anyone was wondering, the club ratings have for some time been based on the KGS system, which has recently been overhauled. Where a player had a solid KGS rating, that was used. Where a player did not, his current handicaps against other players with solid ratings were used to estimate one for club use. This (in theory) has the advantage of giving some idea of relative strength compared to players outside the club, while not forcing members to play online. (In any case, most people know their strength relative to the others they play near their own level, so they don’t even need to worry about any of this.) Of course, it’s not totally accurate, but it generally works out within a stone or two. If anyone has a better idea, let me know.
