Current Elo ratings for the ATP tour. This list includes only those players who have completed 20 or more tour-level, tour-level qualiyfing, men's challenger, or ITF $50K+ matches in the last 52 weeks.
Unlike the official rankings, Elo ratings give credit for who you play, not the round or tournament in which you play them. I've written an extensive introduction to tennis Elo ratings here.
A 100-point difference in Elo ratings implies that the favorite has a 64% chance of winning; 200 points implies 76%, 300 points implies 85%, 400 points implies 91%, and 500 points implies 95%. The overall rating ("Elo") doesn't consider surface, and the surface-specific ratings ("Hard" etc.) are based solely on matches played on a single surface.
To generate forecasts for a specific matchup, use a 50/50 blend of overall Elo and surface-specific Elo. These 50/50 blends are shown in the table as "hElo," "cElo,", and "gElo." The 'default' match type is best-of-three, so in a best-of-five match, the favorite will have a better chance of winning, by a factor that depends on the best-of-three odds.
