I’m using a single-sided crank arm 4iiii PM on a wheel-on trainer. I’ve got my Power Display in the Settings set to “3 sec avg”. When holding a steady cadence during workouts the power is jumping around quite a bit. Is 3 sec power smoothing disabled during workouts?
I’m not exactly sure but I’d lean towards yes. My Neo 2T is synced to Zwift and my Garmin Edge head unit. 3 sec average set on both and when doing the ZA workouts I notice the two don’t match that often. So I’d guess Zwift is displaying instantaneous power during workouts.
