Yeah a good consistent anchor point is EXTREMELY important, and a part of the form I was talking about. Personally I have 3 definite things that I bring string/hand/release back to to ensure consistency. I let the bow string part my nose directly in middle, right trigger finger on the right corner of mouth (right handed), and looking through the peep all together helps me to bring it back to the same exact place every time and keep from canting my bow.
