I can't wait to read your findings. To me, the extra core magnets, like 20 on top of 8, are more important to make the turning less bumpy when those magnets pass each other. Remember that magnet attraction or repulsion forces are not linear, unlike springs, but exponential, and the effect is more pronounced for very high TPS and solve times measured in seconds (for Yiheng! and probably not much at all for me). In other words, for the same amount of core attraction, smaller/weaker but more number of magnets along the path or trajectory can make fast spins smoother, and hence more controllable. It's analogous to driving very fast past a few speed bumps versus a larger number of smaller ones over the same distance.
Now, the number 20 has always intrigued me. Was that number of magnets chosen due to manufacturing difficulty? It seems to me 32 is the right number. You see, 8 magnets, with one in each octant of the sphere surrounding the centre, is evenly distributed. Add more magnets evenly around those 8, and it seems 32 would be right. They will be tiny magnets.
It will be very interesting to see what Moretry can deliver. Manufacturing quality, precision or tolerances will be important with such high numbers and tiny parts to yield the desired effect. I think we should be grateful to Moretry for pushing the envelope, and I wish them more success.
