RE: need help with bare shaft tuning
I recently went thru the same process. This is what worked for me.
I started out with my rest height set at the center line of the bow, thats the hole the rest bolts into. The arrow was exactly bisecting it when viewed from the side. I then set my nock point 1/4" min high. Next I set my center shot by placing an arrow against the machined area of the riseron the insideof whereof where the rest mounts. I adjusted my rest for center shot by makinga nocked arrow and the arrow against the riser pefectly parallel when viewed from directly above. This will get you very close to center shot. It is important to have the nock point above the rest point to start because the arrow can glance off the rest and simulate a high nock point when it is really low.
I then paper tuned the bow and followed with bare shaft. The initial setup can save lot of headaches by knowing up front that the nock point is high and needs to be adjusted down.
