There is no "differential force". At least nothing you could measure. The
teeth are skipping because of inertia in the things that are connected to
them. That is, they don't want to stop when the driving force stops.
Lets say one motor is a 1.0 of max and the other is a 0.8. By your logic,
the 1.0 motor would be "held back" by the other. But that is not what
happens. It is enhanced! Together, you have a 1.8 drive. Both motors are
better because they have a helper. Maybe you don't get 2.0 like you would
with two max motors, but you certainly don't have them fighting each other.
