Torsten,
Thanks. I derived BOTH Spin 1/2 AND Spin 2 (720o) in the video. But like the essay it was all packed in rather tightly! For ease I post the 100 second version here so you can see it again (just different relative rates of z axis rotation).
And yes, the rest was correct, the cosine distribution with Latitude well known in Geophysics and known in marine navigation. The new realization was the inverse and orthogonal relationship of 'curl' (or +/- charge), so also Chiral.
The 3D cascade mechanism squaring the values dawned on me slowly. I'd already looked at QCD and knew the 'squared by a field' effect from there, and experiments, so l knew it existed. The only question was how it was produced. Maybe also training as an architect honed 3D visualization skills - 'seeing' real 3D bodies from 2D images.
In all it was just like assembling a jigsaw puzzle. With all the pieces related in just one of infinitely many possible ways it all suddenly fits together.
On the 'wavefunction' I don't understand "only one". There is one for each emission, or 'photon' (or many very similar ones) and NOTHING is really 'non-local' (leaving the special case 'tomography' out for the moment). As Zeilingers experiments confirm, each 'particle', wave or wavefunction, is modulated on interaction (i.e. a polarizer or modulator) which is a total collapse, to be re-Born (lol) as a NEW function, with NO MEMORY of the old!
I prefer to say "requantized" as a new/re emission'. (It may also be looked as as a local part of a plane wavefront - so we get 'bi/tri(etc)refringence' in diffuse media until the whole wavefront has been modulated - as Raman found long ago). Huygens construction then works fine, and is very much alive and well and central to cutting edge Optics and Photonics, and that's why.
I hope that helps tie up the many apparent loose ends (and sweep away many wrong jigsaw puzzle piece positions and orientations!)
