I suspect your being optimistic with 1/3, might be as low as 1/4. On the other hand back and forth 'pumping' motion is easier to do quickly and with greater force than rotating a wheel since the arm/hand would be optimally positioned and not have dead spots due to biomechanics where the handle is inline with the arm requiring up/down rather than push/pull motion.
Think of a ratchet wrench vs moving a fixed wrench in circles.
