Total time and Running dynamics
Total time would help identify if people were taking long breaks on their workouts.
Running dynamics similar to the ones Garmin connect has. If you added this then I wouldn't have to open another app to view their data.
Running Dynamics data can be viewed in the Scatter Graph. The Scatter Graph is available to coaches and athletes with a premium subscription, and can be added to the File Viewer from the Chart Library.
More information on using the Scatter Graph to analyze Running Dynamics data can be found here:
