Sounds like you are getting there. The cranking of the neck thing. Just this evening i had a go around with my wife, about the same thing. she was jamming her neck going for a long draw and a tight hold and anchor with her recurve. she has been complaining about a stiff cord in her neck. We worked it out much as you described, and she found that the cramping in her neck was not giving as much pain as before. I have had bows that I could squeeze hard and not effect the flight of the arrow,, straight gripped Schulz, and others that worked better with just enough pressure to keep the bow in my hand on release. If you let the bow push too much back on you to the point of collapsing your shoulder that could also be less than ideal. Everyone has there own best exact spot for their anchor, where ever it naturally lands and still allows inline and clear vision works for most.
As far as the comment above, good form is just that, adapting that which works for others that are better than us. We are all the same species, what works for one will generally be similar for another. There is a difference from static target shooting mentality to the fluid hunting mentality, the approach is quite different. Saying that, I will admit to having enjoyed FITA shooting and shooting indoor PAA rounds. That 20 yard 290+ per round average did not help me at all for hunting.
