up to the Boston SCRABBLE® Club
As of the 2000-2001 season, club statistics include only number of wins, number of losses, and average scores for each player. I presume a tie is considered as a win for both players. A more complex system had been employed in the past.
Director Mike Cohen produced one current rating sheet which is observable at the club. He does not email the rating results, as is done by many of the clubs in the Boston area.
Club seasons are from September through August annually.
