Research & Methodology
I used a dataset with over 20 years' worth of match results (here's a link). I experimented with different lengths for each rating period and tuned parameters for volatility. I also developed surface-specific ratings and blended them with overall ratings to decrease variance. The result is rankings that I believe are a better reflection of true skill than the ATP rankings.
