In simulations, is the effect artificially constructed over time, all the pairs of angles of the same differences contributing to shaping the good result?
In real experiments, it is not possible to adjust the polarizers rotations at high speed over dozens of values. It is already a performance to switch at this controlled speed. There are only 2 possible positions per arm, different from one arm to another and adjusted in such a way to find ratios interesting for the Bell inequalities.
The simulations calculate for all the integer rotations in degrees from -90 to 90 ° and therefore analyze all the integer differences from -180 to 180 °. Thus, a given difference is constructed by many pairs.
After verification, the answer to the question is no.
We took the angles set of a known experiment and randomized the rotations only on these values. The results are of the same quality as using the entire range from -90 to 90 °.
I take this opportunity to remind the little interest of new refutations of the communication loophole between the two polarizers. It is better to measure more differences for a fuller curve, the technology allowing it now. Is it not better to check more than 4 points when it is possible ?
