Peter,
A truly masterful essay. A few small problems but you got the major points correct, especially your key points on page 8. As far as I can tell you've worked this out from geometry. I've worked out the same results from the physics of Stern-Gerlach and Gordon Watson has recently worked out the same result from Bell's formulation. We have thus converged to the same point from three different approaches. I think it will be seen to be the correct point.
Of your 10 points, the first two are obvious, and the third needs further interpretation. But points 4,5,6,7,9, and 10 are major, and of course go against the grain of orthodoxy. (Although I believe your approach to point number six is incorrect, your result is correct.) I believe your model of spin one half (720° rotation) is not the correct model, but I don't see that this is any effects on the outcome of the measurements.
The quantum formulation of the singlet state is legitimate. What is not correct is believing the mathematical superposition is physical.
I do agree with Christian Corda's remark above that our understanding of nature is classical, not quantum. Also Steven Tuck, Gene Barbee, and Vladimir Tamari seem to believe (as I do) that classical underlies quantum, opposite to the orthodox view. And I think you have nailed entanglement. It used to be known as conservation of momentum before Bell confused everyone with his naïve formulation.
I put off reading your essay because, knowing that Gordon and I had worked out the Bell problem, I just assumed your treatment would be wrong, and did not relish challenging you. What a pleasant surprise to find you right on target.
And what is most impressive is that you are an architect, not a physicist. Just not brainwashed enough I guess.
Because I've come to the same results by a different path, I can see that you are correct. But I'm not sure other physicists will be able to see it.
My guess is that the 'unorthodox' nature of your essay (meaning, not as a physicist would do it!) will work against acceptance of your results, plus the fact that most quantum physicists are in love with the "weirdness" of quantum mechanics. But you have seen through to the essence of the problem. Congratulations.
Worth a 25, but you will have to settle for a 10.
My very best regards,
Edwin Eugene Klingman
