Power differences between Strava, Garmin & Quarq
Moderator: robbosmans
Last ride my (avg/NP) power was:
Garmin: 213W/231W
Strava: 185W/219W
Quarq: 178W/228W
The difference in avg power between Strava and Quarq comes from moving time vs elapsed time. But how is the difference so big between my head unit and Strava? Is it because my head unit records without zeros? When I compare to other riders who are riding with me (almost the same weight and effort), they have higher numbers on strava but almost equal on their head unit.
I have a garmin edge 530 and quarq sram axs D1 powermeter.
I've read that more users of the edge 530 are have this issue.

Probably yes, recording zero cadence or zero power vs omitting that data entirely while still moving.

Strava does use it own map data to calculate speed, distance, elevation correction, etc. That's why you'll see crazy speeds or elevation if your GPS erroneously has you riding off the edge of a mountain road. I could see how that would would result in a different "moving time."

...and: dont be surprised about diferences in "NP" ("XP" at strava) between "garmin" and "strava", even, if "AP" is identical. they are using slightly different algorithms ("garmin" is always calculating higher numbers).
strava (using the same algorithm like golden cheetah) is closer to reality.
