I have recently done a ride on the turbo and the average power seems to have been recalculated by connect compared to what the edge 520 head unit said live. The average power was over just 300w after 20 minutes, but connect is saying my peak 20 min power was 289w. The only thing i can think of is that i use 3s avg on the head unit, so does it use this to calculate overall avg power instead of the power each second?
the power dropped out a few times, so the 3s avg dropped but not to zero, so if the overall avg is based on the 3s avg there are times where it would use maybe 200w instead of 0w.
