I did a quick workout today, and the active zone minutes on my Inspire 3 doesn't make sense to me. I manually started and ended the exercise on my fitbit watch. See attached screenshots for the two screens below:
Under the workout details:
- "Time in Each Zone" is showing 13 minutes in Moderate, and 1 minute in Vigorous. So I expect my active zone minutes to be 13 + (1x2) = 15.
- However, this exercise is only showing 9 zone minutes? Where are the 4 missing active zone minutes?
Under the Active Zone Minutes:
- This workout is showing as 10 zone minutes (instead of the 9 zone minutes shown in the workout details screen).
- An auto detected activity is listed under 'Other Activities'. This activity is at the same time as the manual exercise I started on my watch, and lists 4 zone minutes. Why is this not counted towards the total zone minutes for the day?
Please let me know if I'm misunderstanding something here.
