EDIT: The more I think about my supposition, the more I think I’m off target.
I don’t know about the wanting to go left or right part (never looked into it; never needed to) but it’s been common knowledge for many decades that setting up a bow for perfect center shot is a huge no-no for finger shooters. That’s why you won’t find any tuning guides out there that suggest otherwise.
I don’t know if it’s been mentioned yet in this thread, but there is an important distinction between center shot and center cut. Center cut is when a bow’s sight window is cut to the exact center of the bow. Center shot is when the center of the arrow shaft is in line with the center of the bow. Because of the diameter of the arrow shaft, the only way to get perfect center shot is to have a sight window that’s cut at least half the width of the arrow shaft beyond center. In reality, the widow would have to be cut ever further beyond center than that due to the thickness of the strike plate.
