84 miles of riding. Well, thanks for that. I agree that it's hard to know exactly what's happening, but it's nice that you're trying.

The power estimates come from the speed. The estimates are close to the same because the time was close to the same.
It comes pretty close to an ideal experiment in many ways. Presumably 10 repeats of each might give more robust statistics
I'm not sure it's "pretty close to an ideal experiment in many ways" at all. Nonetheless, Rides4Beer did 84 miles of riding. You're thinking 840 miles of riding will turn an unscientific comparison into a robust experiment? Hmmm. I'm not sure about that, either.
