Tell ya what Greg, I know form is very important to some folks. But for myself, the more I try to think about what I'm doing when I'm shooting, the worse I get. Just pull it back and let 'er fly.
If it feels comfortable to you and you are hitting pretty good, don't sweat the small stuff brother. Like anything else you do, consistancy comes with lots of practice, and the right equipment.
I believe that, for me at least, the shot just has to happen. I have no idea whether or not my form is "correct" and frankly don't care. Could I shoot better if I adjusted a few things? Maybe, maybe not. Guess I'll never know.
Worrying about things like that is what got me back to shooting trad. after a 20 year trist with a compound bow.
I 'aint trying out for the olympics, and I don't shoot tournaments anymore. I can pretty well hit what I'm shooting at, I know what arrows I need to be using, and that's pretty much all I care about.
Perhaps it IS important to you. If so, I'm not knocking you or any of those folks who work hard at it and I admire your determination.
I just want to enjoy shooting my way I suppose and not worry if my elbow is too high or whatever. If it 'aint fun, why would I want to do it?
Of course all this is just MHO and your mileage may vary :D
