Where significant figures should be applied is on the input values (In Aren's calculations the Free speed, Stall torque, and Spec voltage). All were given to at least 3 significant figures (It should be safe to assume that Spec Voltage wasn't 12v +/- 0.5, but rather +/-0.05 or even better).
And as the motor heats up near the end of a match?
Ohm's law breaks down, and nature takes her tax.
