Tiddlywinks World Ratings

Latest ratings (updated 1 October 2025)

I have implemented a new version of the ratings program, with all calculations backdated to 1985. The new version should be easier to maintain, be more future proof, and also more reliable. You may notice that the range in ratings values is slightly smaller than the previous program (which dates from 2002).
In the background, I am still choosing between some model parameters. I intend to use the settings that give most reliable predictions of past scores (back to 1985) but it will take a while. So please do not be surprised if published ratings suddenly change (slightly).
