Algorithm Steps
Step 1Health Burden
H_eq = 5 + 1.25 × 0 = 5
HealthScore = min(100, 20 × log₁₀(1 + 100 × 5)) = 54
Step 2Risk Score
Risk = 0.70 × 54 + 0.20 × (1 × 10) + 0.10 × (0 × 10) = 39.8
Step 3Fun 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 4Outputs
WorthIt = clamp(50 + 0.5 × (83.14 − 39.8), 0, 100) = 71.67
FRR = (83.14 + 15) / (39.8 + 15) = 1.79
