To what extent will my powerXERT power output metrics change as a function of riding all my workouts at a 4% positive slope? I ask that because of a serendipitous discovery that on my KickR bike smart bike, when the slope on the bike is set to 0%, despite having my fit to the bike professionally measured out, the forward rocking motion associated with adding power output causes me to slide forward on the seat requiring continued readjustment of my seating position. When I elevate the slope to 4%, I no longer experience any rocking forward and aft (presumably Wahoo figured that effect emulated being on the road - sic). Hence, I no longer slide forward out of my calculated seat position and do not have to readjust it. However, I don’t know how that affects Fitness Signature calculations, or any other metrics, or even if it does have any such effect(s). It sure does feel more effortful, but it sure as heck is nice not to be sliding forward on my seat. Any thoughts?
