We measure the speed loss. Robot speed / theoretical robot speed.

We use this number as efficiency. We should also be able to figure out how much power we are loosing. But, I don't think we ever actually calculated that. We were primarily interested in acceleration and top speed (in that order).

The numbers are approximations, due to test noise and limited sample size.

Other data showed us that our 2012 drivetrain was more efficient, such as the significantly increased coast down length over 2011.
