ZWO→FIT Delta is the measurement that makes the closed loop auditable. For each interval in the .zwo file, the system compares the prescribed target to the .fit telemetry recorded against it: power, cadence, heart rate, duration. The Delta is not pass/fail. It is per-interval telemetry. Interval 1 lands at +2W; Interval 2 at -8W; Interval 3 at -34W; Interval 4 at -91W. Each Delta feeds Execution Precision; the cumulative pattern feeds Failure Horizon. Tracked longitudinally, ZWO→FIT Delta becomes the audit trail that distinguishes a 0.94 execution from a structurally correct but physiologically failed one.

Protocols: Protocol 10 — Adaptive Workout; Protocol 11 — Failure Horizon

The metric traverses the closed loop: Intent is the .zwo prescription the system computed against the Athlete’s True Normal. Telemetry is the .fit recording of the executed session. Adaptation is the longitudinal movement of the metric itself, logged against the True Normal and feeding back into the next day’s prescription via Protocol 10 (Adaptive Workout).
