Garmin Rally Power Meter Series

My FTS has been increasing each ride. I thought, wow I'm doing better. Then the last one.. the jump from 180ish to over 230 got me... this... is wrong.. So I think from now on a calibration before each ride is required (for that reason alone I can't give this a 5 star).I was curious if this was broken or my smart trainer which I have been using up until this point had the error (note I have never experience such sudden power improvements on my trainer as I have on the pedals). So I put them both together and did the calibration sequence for both of them. For the trainer it was a spin down and for the cleats it was remove the feat and let it zero. The only thing I didn't do on the trainer was use it for 10 minutes before calibrating it which was requested on zwift. however what I was suspicious of was not the trainer but the garmin RS-100 since that was what was experiencing the shift...Long story short you can see the overlay. There was about a 9% difference. If I am note mistaken RS100 boast a ± 1.0% accuracy and the directo elite a ± 1.5%. MAYBE this difference is due to the fact that I have one foot monitoring power and the trainer is receiving the input of two feat. However... I think there would also be efficiency loss in the drive train to factor as well which would aid the pedals in showing more power. Maybe... my power output is lopsided and one leg is just weaker than the other..I'd expect the accuracy to improve with RS200 since the pull on one pedal will aid the power output as the other pushes but until then I give 3 out of 5. These pedals aren't cheap... high price means high expectations. I shouldn't experience power drifts causing me to doubt accuracy less than a month after purchase.
