I can' t help with the shot question but I have experienced the " hit illusion" also.

Philbert8 and I were hunting out of the same tree when a group of does walked in. He selected his doe and I watched him shoot from just over his left shoulder.

I thought I saw his arrow hit a perfect double lung, just behind the the shoulder, in line with the opposite shoulder. When we retrieved the deer we were both surprised to see his entry point 4 inches back and higher than we both " saw" it hit.

He still got the double lung hit and the doe died at 40 yards.
