I'm trying to understand the Average Power Phase values inside the .fit file. There are four of them, for example
avg_left_power_phase: (355.7812555590821, 199.68750312011724, 202.50000316406255, 97.0312515161133) for certain lap. I assume that the first is the start of the peak phase, the last is the end. But what about those two remaining? Similar four values are for peak power phase, for example
avg_left_power_phase_peak: (59.06250092285158, 125.15625195556643, 66.09375103271486, 91.40625142822267).
I looked to the fit file specs, but there is nothing.
UPDATE - I'm using Favero Asioma Duo power meter pedals. They have implemented all Garmin PCD metrics, except the cleat offset.
