Equibase and Beyer Speed Figures Help Bettors Compare Performances Across Tracks

Speed figures boil a horse’s raw running time into a single index that adjusts for track variance and distance so bettors can compare performances across different racetracks and conditions. The figures are straightforward: the greater the number, the quicker the horse, but translating one provider’s number to another is where money changes hands.

Gregg Jahnke of Quixoteracingstable lays out the practical gap bettors face: “95% of the times I mention speed figures in this blog they will the numbers reported in Equibase, because that is a free database. Beyer figures are more accurate, but costly to obtain.” Jahnke’s house rule is a mental conversion from Equibase to Beyer based on a small sample: “I calculated the differences for about 30 horses from a recent DRF.”

Those mental adjustments are blunt and regional. Jahnke recommends subtracting “10-12 points” from Equibase numbers in the East and Midwest on turf or dirt, and “15-17 points” in Southern California. He qualifies the rules for class bands: “This is only for Beyers above 80, the difference would be greater for cheaper horses because Beyer number decline faster toward 0.”

The industry behavior Jahnke describes helps explain why handicappers treat Beyer differently. His observation: “Go to any big dollar handicapping tournament and you will find 75% using the Daily Racing Form (Beyer), 20% Ragozin, Thorograph, or other, and maybe 5% what we call the program number. That was true 20 years ago and today.” In practice that means paid Beyer access still drives the majority of serious tournament lines, even while many bloggers and casual bettors default to the free Equibase feed.

Jahnke warns about variability that tips the balance toward Beyer for sharp bettors: “Equibase number also have a greater degree of variability, Beyers are ‘smoother’.” He urges caution about one-off high Equibase readings, “Be very careful no to grab just one ‘top’ Equibase number that in higher than the rest. Equibase will have more variability on off tracks, and soft turf.” He also offers sex and program adjustments: “For Equibase I generally use: Fillies are 5- 8 points lower, as are state breds,” adding that on lesser circuits “it might be 10 points lower an Indiana Downs, Lone Star, etc.”

Jahnke frames his rules as pragmatic rather than definitive: “Reasonable people can disagree about these differences, but I think my estimates are close. In most cases the mental adjustment is good enough.” He even translates data into commerce: “I would pay DRF $10 (for a report on the dam) if I were buying 10% of a $200,000 horse, but not for for 2% of a $50,000 horse.”

These conversion heuristics come from a single author’s calculations on “about 30 horses” from a “recent DRF,” and the sample has not been published. Jahnke’s numbers give bettors a working roadmap: treat Equibase as a free starting point, subtract the regional deltas he recommends, and remember that Beyer’s human adjustments aim to reduce volatility, but the exact point gaps still merit independent verification.
