The reason I posted that is because I have replicated the straight version of vtrack
for testing where the single magnet moves.
It is like the SMOT.
Is there anybody else playing with this setup?

No. I have, however, spent time and over $50.00 in parts on my 'brilliant' neo-mag motor. That was when I learned about 'sticky points.'
A co-worker into this scene longer than me said, "yeah, magnets don't work like you think."
Ever wonder how much energy the human hand is exerting upon that stator-magnet to get it over the one sticky point?
Will nearly one revolution provide enough energy to mechanically reproduce the coordinated hand movement to overcome the one sticky point?
I predict that his plan, to make the four pairs of mags incrementally shorter towards the one sticky point, will change the shape of the sticky point. It will weaken where he wants it to but it will also causing the sticky point to engage the stator a bit sooner acting on the last two pairs of tall mags.
Magnet motors, always with the sticky points.
Most of the designs I've seen seem to work on weak to strong magnetic fields. Well i got passed the sticky point on a magnetic ramp design by stacking smaller magnets in a sine wave pattern along the sides of the ramp. The V or diagonal formation of the magnets in most designs could be represented by smaller magnets stacked as half waves (or half sine waves) . So I completed the wave pattern, which kept the steel ball rolling till the wave pattern ended. Worked best in an alternating wave pattern. As one wave completed its attraction and begin to diminish the other took over-one side to the other. If you think about it, it works like us walking with two legs. We begin to proceed forward with one leg and would actually fall to the earth attracting us (or stick to the earth like the sticky point with magnets), but the other leg catches us and pulls us forward --- and so on. I guess the V gate designs would be like hopping with both legs (or in the case of diagonal magnet arrays, like hopping with one leg), thus stopping and going and the need to generate a starting force over and over again. With the alternating sine wave pattern on the sides, as the momentum of the object, in this case the steel ball, carries it a little past the first sticky point--which happens to the wheel in the calloway video-- it?s caught by the attracting field on the other side, back and forth, like our two legs carrying us forward. This brings other ideas to mind. On a down slope it?s easier to walk and pick up speed, gravity and momentum helping us out. In the same way, having the track slope up and down would help the forward momentum all the more.
I've always been told magnetic fields are static. I guess. But even if they are static, by arranging them in these low to high, or wave, patterns---combined with some sort movable mechanism like the smot or calloway wheel----we can create dynamic movement. Like ,as mentioned previously, us walking across the earth. Or like the earth moving around the sun.

Here is what I see:
Magnetic Force - which can generate Torque/Inertia Force ? which can be continued by Oscillations/Wave Patterns ? which can be Designed/Engineered Mechanically.
