Analytical Proof & Invariants

Machine Precision

Governing Mathematical Formula:

Total PPD Award = (Scheduled Weeks for Body Part) × (Impairment Rating %) × (Weekly Statutory Compensation Rate)

Step-by-Step Mathematical Derivation

Statutory Two-Thirds Weekly Rate

Weekly PPD Benefit = AWW × 66.67% = $1,150 × 0.6667 = $766.67 per week.

Compensated Scheduled Duration

Compensated Weeks = Scheduled Body Part Weeks × Impairment Rating% = 200 weeks × 15% = 30.0 weeks of benefits.

Total Lump-Sum Statutory Award

Award = 30.0 weeks × $766.67/week = $23,000.10 tax-free cash award.
