Ragozin Sheets — Professional speed figures developed by Len Ragozin that measure a horse's performance using an inverse scale (lower is better). Known for precise track variant calculations and accounting for energy expenditure beyond raw speed.
What Are Ragozin Sheets?
Ragozin Sheets (commonly called "The Sheets") are professional-grade speed figures developed by Len Ragozin starting in the late 1960s. While less well-known to casual fans than Beyer Speed Figures, Ragozin Sheets are highly respected among professional bettors, racing syndicates, and serious handicappers.
The key distinction: Ragozin uses an inverse scale where lower numbers are better. A horse running a "3" has performed better than one running a "7." This mirrors golf handicapping and represents a fundamentally different philosophy than Beyer's higher-is-better approach.
Ragozin figures are also known for their meticulous attention to track variant calculation and their consideration of factors beyond raw speed — including how a race was run and the energy expenditure involved.
Ragozin vs. Beyer: Key Differences
| Factor | Ragozin Sheets | Beyer Figures |
|---|---|---|
| Scale Direction | Lower is better | Higher is better |
| Typical Range | -5 to 20+ | 50 to 120 |
| Availability | Subscription required | Published in DRF |
| Energy Factor | Considers how race was run | Final time focus |
| Track Variant | Proprietary, highly detailed | Standard calculation |
| User Base | Professionals, syndicates | Recreational + professional |
How Ragozin Sheets Work
Ragozin figures start with the same basic premise as all speed figures: converting race times into comparable numbers. However, several elements distinguish the Ragozin methodology:
1. Track Variant Precision
Ragozin is known for meticulous track variant calculations. Every race on every day is analyzed to determine exactly how fast or slow the surface was playing.
2. Energy Expenditure
A horse that sets blazing fractions on the lead uses more energy than one sitting comfortably in the pack. Ragozin considers how races unfold, recognizing that two horses with identical final times may have run very different races.
3. Pattern Recognition
Ragozin encourages users to look for patterns: horses bouncing (regressing) after peak efforts, horses improving in predictable cycles, and horses whose style suits certain race shapes.
The "Bounce" Theory
Ragozin popularized the concept that horses often regress after career-best efforts. A horse running their best-ever figure may "bounce" in their next start as their body recovers. This insight has influenced modern handicapping across all speed figure systems.
Reading Ragozin Sheets
Ragozin figures typically range from about -5 (exceptional, elite) to 20+ (below average). Here's a general guide:
- -5 to 0: Elite performances, Grade 1 caliber
- 1 to 5: Very strong, graded stakes quality
- 6 to 10: Above average, allowance/stakes level
- 11 to 15: Average, solid claiming horses
- 16+: Below average performances
Remember: context matters. A "10" might be exceptional for a $10,000 claimer but poor for a stakes horse.
How AI Uses Speed Figure Systems
Traditional handicappers compare Ragozin or Beyer figures in isolation. RaceHP's neural network integrates multiple speed figure systems with 144 other features to find non-linear patterns humans miss:
- Cross-system validation — When Ragozin and Beyer agree, confidence rises
- Bounce detection — AI identifies regression patterns across figure systems
- Energy modeling — Pace and running style factored into predictions
- Value spotting — Finding horses whose figures suggest they're undervalued
