Let users specify whether moving time or elapsed time is relevant to that activity
When runs or rides are uploaded to Strava, time spent stationary or with very little movement is ignored when evaluating the whole average pace of the activity. So for example, a run last night where I had to stop for 50s to tie some shoe laces ignores those 50s when calculating the average pace.
For running, I think this gives a misleading impression of pace. I can run 5min/miles for a mile, providing I run for 15s, stop, run for 15s, stop, run for 15s, stop, etc etc etc. And if I recorded such an activity on Strava, that's what the activity would show.
I would like to suggest a toggle switch for an activity - "Elapsed time or moving time" - which can be specified on run by run basis so that if I want to see my pace based on total elapsed time, I can; and vice versa.
I strongly suspect that this would be a feature only desireable for runners.
