The gearhead sets the ceiling of a configuration.
Its rated output torque is a limit, not an operating point: it is the number a configuration is sized under, and the reason a torque margin is worth reading before a speed. Stage count carries the rest of the story, because each stage adds backlash, drag and a loss.
