SMOT Gravity Wheel

I  totally agree with your argument.   As you said  the distances would be the main criteria here.   The distance between the balls should be adjusted such that when the top ball leaves the track,  the bottom ball should be attracted towards the track. ie.,  any decelleration of  the top ball when it leaves the track should balanced by  acceleration of bottom ball which is attracted towards the track.

Unfortunately,  the balance (as you describe above) is not good enough in this setup :  when you have a balance achieved between deceleration and acceleration, then all you have done is you have compensated the negative effect of the sticky point.  What you need is a positive difference (that should include friction and air drag at least) between the two counter-forces to keep the rotor disk in a continuous rotation.
Re on the distance:  I agree, the distance between the ball magnets is one important thing, however I refer to the distance in space between the last (stationary) magnets of the SMOT ramp and the just leaving ball magnet too.  This may sound strange but just think the curve steepness of the SMOT ramp: it may have to be ,say,  ellipsiod-like at its upper end instead of a circle.
(This is a visual speculation from me.)

I'm somewhat convinced that part of SMOT physics
involves the rolling motion of the runner against
the ramp. This is what creates an out of phase
cross-product drive of the magnetic and gravitational
forces. Just "passing-by" is probably insufficient to
simulate a smot mechanism.

Your diagram has insufficient detail to show that you recognize
this or not.
