The Performance Index is exact arithmetic over published benchmark tables. No model, no weighting nobody can see — every figure is recomputable by hand.
Privacy by Role
An athlete reaches only their own record; the API refuses another's rather than hiding it. Guardian consent is recorded against a child's record where it was captured.
Data Quality Is Explicit
A value outside human limits is rejected, and an unusual but possible one is held back until a coach confirms it — each with a reason, never averaged in. The report says what was excluded and why.
WHO Growth Reference
Under 18, body composition is read against the WHO BMI-for-age tables by month rather than an adult cut-off applied to children. From 18, adult BMI applies.
National Aggregate Is Planned
A cross-state rollup, participation rates and a pipeline funnel are planned, not built. Nothing in the product aggregates beyond one athlete today.
Trends Per Athlete Only
An athlete's dashboard charts each test across their sessions once three are measured the same way. Trends across a population are planned, not built.
