Only thing on the vid I see is that, first, you might take just a bit longer to settle at anchor and solidify everything. Some people shoot fast, there's nothing wrong with it if it works for you, but it helped me to pause a bit and then focus on continuing back tension, rather than just being static. Second, I say this because your hand does start to move forward just a fraction before the shot goes off. I found that after incorporating the things Arne shows in his vids, my draw got a bit shorter, as I was apparently overdrawing and sinking, rather than anchoring and continuing to use my back through the shot. These are just observations, for what they are worth. Good luck. Paul.
