adjust your nock height very little, the fletched shafts are compesating for the nock set, the bare shafts will magnify the adjsutments needed, although you are very close. keep in mind a bow that is cut to center or just past will shoot a stiffer arrow well. After you think you have them tuned get some very wide broadheads and shoot fieldpoint fletched arrows and then see where the fletched broadheads hit, you might have to do some minor adjustments, Although I would try and just get close now wait till you can shoot outside and get a better feel for whats going on. a little further will magnify things and give you a better idea.
