The suggested 15min warm up then spin down calibration gives me excellent results (+1W) comparing Wahoo in TR to Stages on Garmin in the same time frame but not over a longer period of time. I “warmed up” at 170W. What would happen if I warmed up at 280W? Would that result in a higher temperature and a different calibration point? With different input or different time to warm up I’ll get a different calibration value. Will it ever reach a steady state temperature? I can’t believe the Kickr does not have temperature compensation. How can they claim +/-2% accuracy without it?
I am going to try Power Match now. If it fails to work this time I think this thing is going back.
