Every digit that you include beyond four becomes irrelevant, it is just calculator detritus.

Those are desired values, not measured values, and should not be considered when doing significant figures. It's assumed that Ether wants those values as close as possible.
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).
It's cool to see that Shaun White is an active team member (6th person from top left). That guy must be amazing, as he can win a gold medal in snowboarding while also being active on a FIRST Robotics team. - Andy Baker [more]
