RE: Paper tuning Question
It's the 'teeter totter' effect. The hole is generally a good inch over the top of your hand already, which would be the fulcrum. You're pulling behind the arrow, so the center of pressure for your hand is lower than the center of pressure for the arrow. That places an unbalanced load on the limbs from the get go. Lots of bows that I've shot with the limbs set to even tiller want to rock backwards in your hand during the draw, because too much pressure is being loaded on the top limb.
Raise the arrow above that hole, and you just increase the unbalanced load on the limbs. You can tune the tiller to compensate, but that means backing off on the top limb bolt, which reduces the draw weight. I'd rather minimize the problem and maintain the draw weight rather than add to the problem and slap a bandaid over it.
