It allows more torque at a higher motor speed... But your forgetting that the other robot is sitting there stalled. Stall = much, much higher current draw.

And seeing Ethers past contributions, like his recent tests on the speed controllers at Whirlpool's motor lab, I'm going to go with him on this one.
