But that's a rather small difference.

Yep small difference indeed.

Agreed on the importance of effectiveness. Not only proper gearing, but don't forget real-world losses. 1-5% per gearstage and/or chain drive. Properly designed and supported systems can get quite efficient. Gearboxes made with hand drills and drill-presses often are not.

The 200W is quoted off of MK's motor database that uses 10.5 volts from a power-supply. Yes your battery may be as high is 15 volts (300W), but by the end of the match, with a high load, I wouldn't count on it.
