I’m anticipating some negative comments about going into the weeds on this. I, for one, very much appreciate it! Interestingly, I tried to fit v^3 in my model of Strava watts, and v^2 was a significantly better fit. Whether the Strava estimate is good is a different question. It doesn’t account for wind speed or air temperature, so we know it’s missing a couple of marginal effects. Super interesting to me that people are converging, analytically and anecdotally, on 16mph (25kph) as something of a magic wall.
