About 18 months ago, I switched from a wheel-on trainer to a direct drive. Almost immediately, I realized the wheel-on trainer was overstating my power, sometimes significantly. I'd like my power curve to only reflect rides on the new trainer. I know you can delete records one by one, but that's going to take a long time. I am wondering whether there is a way to set the power curve to only display values after a certain date? Or, failing that, to reset it entirely so only new rides going forward count toward it?
