Trial and error is one thing. Knowing what you're shooting for, because you did some calculation first, is quite a different (and much better) thing.

I believe Ether's number are based on actual lab trials.
I.e., the specification provided by Tetrix was no where near sufficient to extrapolate to a 10.8 ft/sec estimate. It was only a team member that went in a lab with dynamometer capability and did lab trials with and without the gearbox attached that allowed for the calculation.
Thank Richard for the creating the data AND sharing the data that allows physics teachers to let this rise above tinkering status.
