It seems that all three have linear progressions. Did you expect the "Progressive" setup to be exponential?

Also, will you plot Speed vs Power as well? I'm curious to know if the power required to maintain the same speed is the same no matter what the gearing/cadence (e.g: How much power does it take to maintain 30mph on 50x15, 50x14, 50x13, and 50x12?). Or if acquiring the speed with different gearing/cadences calls for different power.

I think if you import into Golden Cheetah, you can get torque values as well. That way you can separate the torque from the cadence in the power equation.

Also, if you do that, you'll notice that torque drops off a cliff at a certain RPM It's because we can't fire the muscles fast enough to produce significant torque.
