Assessment Methodology
Calculation Steps:
- Identify Line Horse - consistent performer used as reference
- Calculate WFA Allowance based on age, distance, and month
- Apply Drag Adjustment for beaten margin
- Calculate Actual Weight Performance:
Weight - Drag - WFA - Compare to Line Horse to determine race rating
- Apply special rules (maiden caps, layoff allowance)
Key Formulas:
- Drag Effect: Varies by distance (see Benchmarks page)
- 1 length ≈ 1kg at 1 mile (1600m)
- WFA Scale: Based on Admiral Rous's 1855 table
- Rating Points: 1kg = 2 rating points
