I didn't completely read every post but I'll chime in. Not knowing anything about you except that you are a novice I have to ask about the bow's draw length. 31"? Are you really that tall and lanky? How did you determine the draw length you should shoot? Please measure your wingspan and divide by 2.5. This should help you determine if you're close. If you are of average dimentiones you don't need a 31" draw till your wingspan measures around 77-78 inches or 6'5", which often correlates to your height (but not always).

Nothing will throw off accuracy quicker than too long a draw. It plays havoc with trying to develop any kind of consistent form and/or anchor points.

Couple that with maybe too much peak weight and you'll never achieve any kind of consistency.
