Let's assume your bow is set at even tiller. Your groups are decent at 40 yards, but can be improved. You add 1/4 turn to the top limb bolts (in effect raising the nock). Your groups tighten up. You go another 1/4 turn and bingo...the sweet spot. My question is this: assuming the bow isn't any steadier with a 1/2 turn, would it be better to go back to even tiller and then either raise your nock or lower the rest (assuming clearance is not an issue). Or would you leave the bow as is?
