How the PD Value Engine models the rating.

A permanent-disability rating turns on a chain — whole-person impairment, the rating string, adjustments, and apportionment — where one mis-set value moves the award materially. The PD Value Engine builds that chain explicitly: WPI → the 1.4 future-earning-capacity factor → occupational variant → age modifier, modeled as a PD percent and a dollar value. It shows the strict-AMA reading beside a rebutted alternative (Almaraz-Guzman / Ogilvie) and the PD/$ swing between them, with apportionment carved out under Labor Code sections 4663–4664. Rating figures are projections the attorney verifies against the current schedule.

What WC does.

1. 01

   Justine assembles the rating string from the impairment number through the FEC factor, occupational variant, and age — each step shown so the attorney argues from a transparent computation, not a black box.

2. 02

   Apportionment is a visible carve-out under Escobedo: industrial vs. non-industrial causation per the physician’s percentages, with the award shown before and after the disputed apportionment.

3. 03

   The strict-AMA rating and an Almaraz-Guzman / Ogilvie rebuttal are modeled side by side, so the attorney sees the PD-percent and dollar swing a rebuttal is worth before pursuing it.

4. 04

   Life-pension threshold crossings are flagged for the attorney to confirm.

5. 05

   Occupational-variant, age, and pre-2013 rating tables are treated as values to verify against the current schedule — the engine self-labels its output as a projection, not a certified rating.

6. 06

   Georgia (AMA Guides 5th) and Texas (AMA Guides 4th) rate on their own benefit schedules; this page details the California engine — the deepest of the three.

The AI reasons; the attorney decides.
