BobCo,
I have to disagree with your "plateauing" statement above. I started out with no idea about how to shoot a trad bow. I figured it was just some "gift" that some people were born with.

But reading his book helped me to understand shooting instinctively. I did what he told me in the book and I learned what instinctive shooting was all about. I can now pick up any bow and after a few shots hit what I am shooting at. It's not magic, like I thought it was, it is learning. There is no hocus pocus or phony spiritual stuff in his book. It is knowledge that you need to learn. And with his book I learned fast.
