I don't worry about form, I draw, bring up my bow and release on what I am shooting at, and my bow arm does what it does. Shot after shot, I still put them where they need to hit. Don't confuse the modern bow follow thru with what we do. Traditional shooting is a mental game, and to much thought process will leave you thinking your making mistakes.
I don't think about what I am doing, I focus on what I am shooting at and that is why its called instinctive shooting.
