Condition Multiplier

Condition reads like
a pressure gauge.

Five hard-stop zones. One brass needle. The needle’s position is the multiplier — and the multiplier rewrites the component’s effective remaining life.

Default reading shown is “Fair” (1.00×) — the component lasts exactly its expected lifespan. Slide the rating one zone right and you gain 10% life. One zone left and you lose 25%.

Five zones. Five multipliers. Five playbooks.

Each zone changes how the verdict engine reads the component — and what it tells you to do next.

Same age. Wildly different lives.

The multiplier resolves a 20-year HVAC into anywhere from 26 to 10 years of effective life depending on its condition grade.

Two real components, side by side.

Same multiplier table. Two very different verdicts.
