PDC Type I: Unreasonable "Elements of Reality" in Bell Tests?

[DrChinese]

..The “C” formula is measuring all the photons all the time because it is a polarizing beam splitter that does not destroy any photons like a polar filter does; And is measuring small “v” photons as well as small “h” wrt a vertical alignment mark on the beam splitter.

Thus when the beam splitter is rotated to 90° from its perspective it has “h” in alignment with “V” as defined by the single crystal and 100% of the photons are detected as “h” by the detectors behind the two outputs of the beam splitter (not photons as ‘lost’).
I’m ok with the form of “C” ; it makes sense.

Yup, that's it!

As to the question of 2 laser sources versus 1... I don't really know what the result would be, I'd be guessing. The issue I am raising is the parallel versus series mainly, as that comes to the crux of the issue I would like to highlight.

And IMO QM Parallel and Series the same if only one laser is useded, for QM to see a difference two lasers are required - and no Bell State will be seen with two lasers.
