I'm not sure what the deal is Curt...I am certainly not a short bow expert, having shot longbows most of my life. I do know that the shorter the bow, the more the little things seem to magnify, but heck, I'm having fun learning right along with you.
I do know (I should) that the bow is built with the center of balance....the intended pressure point while drawing the bow...in the center of the grip area, and appropriately tillered from there. Therefore, moving your pressure closer to the shelf, like a higher wrist grip, will have some effect on the nocking point of the string...same as a 3-under shooter has to adjust. But if you can get it all figured out, then it really don't matter. As long as it will shoot for you, who cares! It does make me scratch my head that it bareshafts so well, then kicks with fletches. There are more experienced and capable folks on here that can help you with that, for sure.
Keep us posted.
