Algorithm Steps

Step 1
Health Burden

H_eq = 5 + 1.25 × 0 = 5

HealthScore = min(100, 20 × log₁₀(1 + 100 × 5)) = 54

Step 2
Risk Score

Risk = 0.70 × 54 + 0.20 × (1 × 10) + 0.10 × (0 × 10) = 39.8

Step 3
Fun Score

FlowAdj = ((8 − 1) / 9) × 100 = 77.78

Fun = 0.45 × (4.3 × 20) + 0.25 × 77.78 + 0.20 × (9 × 10) + 0.10 × (7 × 10) = 83.14

Step 4
Outputs

WorthIt = clamp(50 + 0.5 × (83.1439.8), 0, 100) = 71.67

FRR = (83.14 + 15) / (39.8 + 15) = 1.79
