Strong language ?
Maybe the wet dream mention ...
Excuse my french ...
Bike engines are tuned towards big specific power, the Surface is not too easy to determine and the drag is definitely empirical so I like to double check the results of the calculator to alter the coefficients according to actual measured performance (like top speed).
As for the limited measurement, the difference was that big that there is no contest.
And bikes usually have a 1/3rd reduction in the sprocket so 1/1 would be interesting to say the least ...
