Abstract: Since its inception in 1973, the ATP computer ranking system has been the standard by which male professional tennis players have been judged. The ATP Ranking has been used as the basis for acceptance of entries and seeding for most major international professional tennis tournaments. Prior to 1990, a player's total points were divided by the number of events he played with a minimum divisor of 12 tournaments. Since 1990, the ATP Tour has used the Best 14-system which ranks a player based on the total points he earns from his best 14 events. The ATP Tour is currently evaluating new systems, such as Next 6- and 3+3-system.

Abstract: The United States Chess Federation (USCF) rating system, originally developed by Elo, is essentially a simple linear filter. Versions of this system are used by a variety of other organizations, including the World Chess Federation (FIDE) and the US Table Tennis Association. Over time it has become clear that the system does not account for important sources of variability associated with identifiable characteristics of competitive chess players, such as the greater variability of weak players' abilities, and the potential for rapid improvement of scholastic players. This talk discusses the concerns with the earlier system, and the details of the recent overhaul designed to address these issues.

Abstract: The rating system used by the NSA was developed in the early 1980's mainly as a mirror of the chess ratings system. In this talk we discuss some of the differences between the chess and Scrabble populations and the differences in the ratings systems. Performance of the system through 1997 will be displayed and discussed. Also: Post-analysis of 1992-1996 data using some recently suggested methods, and some recommendations of the 1997-1998 NSA Ratings Committee that sprung from these analyses.
