I am thinking of adding ratings to Game Courier. These would be for individual players on a game by game basis. For example, you might get one rating for Chess and another for Shogi. I could go with the Elo method, but I would like to use something that is better suited for calculating a rating from a collection of logs. The Elo method, as used in Chess, gives each player a number, which gets modified after each game he plays. This is suitable for something as large and uncentralized as Chess competition, because it doesn't require full knowledge of all Chess games played between people, and it is simple to keep track of when you simply modify it after each game. But since I plan to write a script that will have access to all logs, and since datestamps on logs can sometimes change, especially if the site ever moves, I'm thinking a simultaneous, holistic rating system would be better. This would freshly calculate a rating based on all game logs without consideration of what order they were played in. Does anyone know of such a system already in use anywhere? Or does anyone have any ideas on how to do what I have described?
