Speed figure conversions help compare horses rated on different systems. While not exact, a Beyer 100 roughly equals Timeform 125, BRIS 95, or Ragozin 2. Each system uses unique methodologies, so treat conversions as approximations.
Published in Daily Racing Form. Most widely used US system. Higher is better. Kentucky Derby winners typically earn 105-112. Created by Andrew Beyer.
Premier European rating system since 1948. Uses pounds-based scale. Frankel earned 147, the highest flat rating ever. Stayers rated slightly lower.
"Sheet" figures used by serious handicappers. Inverted scale where lower is better. A "0" is exceptional. Popular with professional bettors.
Speed figure conversions are approximations. Each rating system uses different methodologies, track adjustments, and calculation methods. Use conversions as rough guides rather than exact equivalents.
In Beyer Speed Figures: 100+ is elite (Grade 1), 90-99 is stakes quality, 80-89 is allowance level, 70-79 is claiming races, and below 70 is lower claiming. Derby winners often run 105-110.
Ragozin Sheets and Thoro-Graph use an inverted scale where lower numbers are better. A "0" is exceptional (Grade 1 level), while "15" or higher indicates lower-level competition.
Timeform is the leading UK/Irish rating system. Their scale goes higher than Beyer (up to 140+). A Timeform 130+ is exceptional, 120 is Group level, 110 is Listed/handicap quality.
Calculations follow the published mathematics of the game — combinatorics for cards, probability theory for dice, and expected-value accounting for wagers. Results are verified against independent references (primarily Wizard of Odds). No calculation here is an opinion or recommendation; it is arithmetic applied to the rules of the game.
