What is Ratings Central
Ratings Central is a state-of-the-art, fully automated, online rating system that is very accurate, is open to anyone anywhere, is extremely easy for tournament organizers (event directors) to use, and provides extensive, detailed, accessible information on events, matches, results, ratings, and rankings.
Ratings Central uses a sophisticated rating algorithm developed by David J. Marcus, Ph.D. that fairly and accurately rates all players, from world-class to beginner, from those who compete regularly to those who compete infrequently. The algorithm was originally developed at the request of the United States Table Tennis Association.
The purpose of Ratings Central is to make ratings more immediate and exciting for all table tennis players, while making it as simple as possible for tournament organizers (event directors) to run tournaments and to submit the tournament results for rating.
Most States in Australia have now adopted the Ratings Central system.
All Sanctioned tournament results and Pennant results are submitted to the Ratings Central website for the purpose of calculation of the player ratings.
Rankings vs Ratings
The Ratings Central system is a ‘rating system’ that provides a means of rating players throughout Australia and the World. The system is not a ranking system and is not used by TTACT for the purpose of State Team selection, or for State rankings or for seeding State and Sanctioned tournaments.

How the Rating System Works
The rating system uses standard concepts and techniques from probability and statistics. This makes the rating system quite different from (and more accurate than) almost all other rating and ranking systems. Detailed information on how the system works may be found from the Ratings Central website.
Zermelo and Cantor
Ratings Central is available for use by anyone and already is being used by several affiliates to create ‘Ratings’ for players in their own pennant competitions.
The following two associated software programs may be downloaded from the Ratings Central website for the purpose of exporting results to Ratings Central:
1. Zermelo
2. Cantor
Zermelo is an excellent program that is used to automate the conducting of a tournament. This program, or the CATTS program, must be used to run either State tournaments or Sanctioned tournaments conducted in ACT. The reason for this is that these programs facilitate the automatic uploading of the tournament results to the Ratings Central web site.
Cantor is a program that facilitates the uploading of pennant style competition results to the Ratings Central web site.
