Looking at the original Garmin fit file, the power stream that intervals pulled was for a connect IQ field called “Average Power” which has the same 0 values across the activity except for a bit of power at the very beginning. Not sure why the average power was so wrong for this activity or why it’s even recorded as a Connect IQ field.
My raw power meter numbers look correct and this activity records fine on the Garmin side.
I tried changing the power stream used in Actions → Activity Settings but it only shows one stream available.
Intervals.icu is getting mixed up with the current_value(watts) field. I need to cleanup that code a bit to sort it out. Will do this weekend. Been avoiding that job for ages but it is a pre-condition for supporting custom activity traces from the fit file.
This issue seems to be coming up again.
I have intervals of 0 power. That also renders inaccurate Load data and then the Fitness graph gets screwed.
I have to manually input my Load as calculated by Garmin to get the Fitness graph to make sense but still you calculate load in a different way so I am still not looking at the correct graphic.
