Hi
I have a stages power meter which recorded my power for a ride today on both a Garmin watch and headset. Both recorded 208w average. I had no stops and the Garmin and Strava time was the same, 1:42. However on the Strava app it has logged my ave watts as 181w. 27w lower than both Garmin tools. On the Garmin website it has recorded 199w weighted ave power. Very confused??
