RE: Is "center-shot"....."center"?
Some drop a way rests will require you to set your nocking point so the arrow is above the berger hole rather than in the center of it in order to get clearance. Especially some of the ones that sit over the shelf instead of behind it. To do this you will have to change your nocking point and peep position, both will need to go up. You will most likely have to resight in as well.
