I made 3 "indoor rides" today with a couple of pauses using the STOP button on my Garmin Edge 530. It was saved after the third ride.
The result in Garmin vs. Strava is:
Obviously, in Strava the elapsed time is used in avg. speed calculation. This is a horrible bug. E.g. if concentrating exactly on avg. speed during an indoor cycling, the record is totally useless.
Why the elapsed time is used in calculation instead of the moving time? It makes no sense.
