How it works

Small surface. Clear chain of proof.

Normalize

Align weight, nutrition, workout, strength, and scan observations to one period.

Triangulate

Require body change plus non-declining results for all three named lifts.

Explain

Report the conclusion with uncertainty and the evidence that supports it.
