# Progress Analysis Guide

Use this reference to keep progress reviews evidence-based and comparable.

## Supported Observations

- Training recency and frequency from completed-workout timestamps.
- Exercise exposure and repeated movement patterns.
- Changes in reps, time, distance, or load when the same exercise and compatible units recur.
- Session duration when valid start and end timestamps exist.
- Active-plan progress exposed by `list_client_workout_plans`.
- Trainer-note context only when the trainer explicitly requested it.

## Comparison Rules

- Name the review period and number of workouts retrieved.
- Compare like with like: same exercise identity, measurement type, and compatible units.
- Label calculated values and explain their basis briefly.
- Treat absent sets or workouts as missing data, not zero performance.
- Report adherence only when scheduled expectations and completed-workout mapping are both available.
- Use cautious language for small samples or inconsistent records.

## Unsupported Inferences

Do not infer:

- an injury, diagnosis, or recovery status;
- effort, motivation, or intent;
- causes of missed training;
- a plateau from a single session;
- adherence when the expected schedule is unknown.
