I am learning that [again old dog, simpler tricks] but at least I saved some money for my "pat on the back" number
I will say it is much more work to interpolate effort/work onto a once-per-second speed delta and then factor in the whole ^3 air resistance thing. And yes, I'll prolly just be lazy and look at the power plot.
Maybe power meters are really only for the domain of training in zones. I do know precisely how many beer calories I am allowed each day though.
