"The R/G choice in the experiment is subjective (no law excludes that as a classical!)"
No, but dependence on Bayesian interpretation runs into the same limitations as the "QRC." There is a built in assumption of nonlocality; i.e., because no communication passes among the participants, the local outcome of one group is disconnected from the nonlocal outcome of the other. The results are not pairwise correlated, only statistically correlated on the assumption that pairwise correlation is observer created, and nonlocality is a physical fact. In other words, "proving" only what one assumes.
Any variation of the ill conceived "QRC" is vacuous.
" ... and I also pointed to the shortcut, which is not only non-subjective but mathematically complete and precise; by computing the cosine numbers shown beside each angle. Occam rules!"
Since you haven't presented any mathematical theory, I fail to understand how you find it mathematically complete.
"What has not been possible in the past is any classical 'rationalisation' of WM results."
That's just the thing, though, Peter -- we don't rationalize the results of a classical experiment. The results have to be 1 to 1 correspondent with the predictions of the mathematical theory.
