I have a KK trainer and have been cranking down the tension as the manual directs until the tire barely or doesn't slip when I grab the wheel and give it a good 1/4 rotation. This results in noticable tire deformation at the roller. Doing this I've gotten my apparent FTP from 230 to about 280* since last October. This last weekend while warming up for a race in Phoenix, a teamate told me I was nuts and to just give it tension but without any real tie deformation (from cranking down). So I come home and try it and suddenly my power numbers are way up and my apparent FTP is now 310-325* or so. The tire slips easily by hand, but not noticable while peddaling, except possibly at the first strokes of a 1 minute max pwer interval.
Which is the best way to tension the trainer and should I belive the numbers with less tension or crank it down and keep working?
*power I can hold for a 5 minutes interval without major difficulty.
