Superb article and very relevant. Lately i been been a zwift fan using wahoo 1gen kick trainer. I have a favero bepro single left pedal and oval rings. No herre is the issue:
Wahoo watt Value constant show a lot (a least 15% i gess) more than my pedal value on the garmin 520.
Have tryed static calibration + Dynamic on the pedals. Did look into ud the pedal lenght is ok (ude 175mm).
Alway preform a spin Down before Amy ride in zwift. Igen tryed a spin Down in Wahoo fitness app
So how to deal with this?
Could use pedal watt in zwift byt then the price a lover FTP.
