Compliance
Offer a more sophisticated workout compliance analysis.
This would specifically be for structured workouts.
For example, if the plan/coach has set a cycling workout with a mix of warm-up, easier zone durations and some higher intensity sets (eg. 6 x 3min at 110% of FTP / with 1 min rest) ... then could compliance be reported on following the structure of the workout.
Eg. I could complete the workout at the allotted duration, or TSS for that matter, but have done so without adherence to the structure. Ideally this could be reported on a per workout basis or across a user defined time period. It's not just training, but actually do the right training correctly.
