I often track workouts with my Fitbit versa but far to often forget to stop tracking. Once on the Fitbit app I will often set the time so it covers the correct exercise period. This does not appear to change the number of calories burnt when I change the elapsed time, it remains at the full value.
maybe it would be an idea to add a default max workout time you can set. If you get near it the watch vibrates to remind you you may want to stop it
