Thanks for the additional science, Ben! In the Charlie thread I originally put "cube" and then thought, "am I remembering right? sounds like I'm exaggerating...", so changed it to "square". But, cube it is. I don't have a watt meter so didn't want to bring watts into it, but yeah, the watts measurements line up. I reverse-engineered the Strava watts estimation, based on speed and vertical, then modified it to account for air temperature. I don't know how accurate my resulting model is, but I only use it for making relativity comparisons, so as long as it's internally consistent for me, it suits the purpose. Strava says my 16mph ride was an average 98 watts. Worth noting that I weigh about 60 kilos.
