Recording power data from Power Tap P1 (Dual) pedals, Garmin 745 (purchased new 24 June '21) records data at least 150, to 200 Watts below actual effort. I am recording on two independent Garmin devices: Garmin Edge 1000 and Garmin 745. This 745 consistently records power data well below the recorded power on the Edge device, on average, approximately 150 to 200 Watts below.
What is the problem? I have zeroed out, or turned off zero data averaging on the 745.
