I had noticed my average speed (on bicycle rides) is consistently lower than what my odometer tells me, more so if I happen to stop during the ride (and how long the stops are). To confirm my suspicion, I downloaded the raw data (not the .tcx or .gpx) and noticed that there are "auto" start/stop events, and the gps data is tracked even when I'm not moving (between auto_stop and auto_start) and apparently is included in the calculation. Removing the data between auto_stop and auto_start gets my average speed much closer to the odometer readings.
Is there a way to obtain the .fit data so I can modify/upload an edited version?
