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
