Here's a specialized performance formula optimized for the given data fields (E-Speed, Finish Positions, Jockey-Trainer %, and Earnings): Horse Performance Score (HPS) HPS=(ES100×0.45)+(AF10×0.30)+(JT100×0.15)+(EMaxE×0.10) Where:

  1. ES =AVG E-Speed Figure (0-100 scale)
    • Direct use of listed E-Speed (already normalized)
    • Example: 85 E-Speed = 85/100 = 0.85
  2. AF = Adjusted Finish (0-10 scale) AF=10−(∑Last 3 FinishesTotal Horses in Those Races×2)
    • Example: Finishes [1st/8, 1st/7, 5th/9] AF=10−(1+1+58+7+9×2)=10−(724×2)=8.42
  3. JT = Jockey-Trainer Win Percentage (0-100 scale)
    • Direct use of listed percentage
    • Example: 50% = 0.50
  4. E = Earnings per Start (Normalized to highest earner) E=Individual Earnings StartHighest Earnings Start in Field
    • Example: $13,376 (highest) vs $4,309 E=4,309/13,376=0.32
