Frequently Asked Questions
How accurate are speed figure conversions?
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.
What is a good Beyer Speed Figure?
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.
Why are Ragozin/Thoro-Graph figures inverted?
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.
What is Timeform rating?
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.

How this works
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.
