Many amateurs have performed this test and found 1-4 photons reflected. You could attempt it yourself.
That is not the issue.
The issue is your claim that it is the exact amount you would expect in FET with a close moon.
Can you show that this is the case, and it is not in fact the amount you would expect in RET with a distant moon?
Because the moon is closer, so more photons would be reflected than in RET.
So you would expect more than 4 returning.
You claimed 4 was the exact amount you would expect under FET. PROVE IT or admit you were lying.
