That is a work of art.
I can't figure out what is going wrong because I sincerely don't catch myself flinching.
You are not watching the front sight lift when the shot goes off, as you learn to you will see what you are doing wrong and be able to call your good shots and see/feel what you are doing wrong on your bad ones.
It does not matter where the sight is at any time, except at the time when the barrel starts to lift in recoil.
