Too many variables to tell right off hand.

I found that paper tuning is somewhat of a pain in the butt since you aren't always sure why an arrow is nock left. Is the rest too far right so the arrow is getting shot that way, or is it too far left so the fletching is hitting the rest and kicking it back the other way. You get my drift...

If I were you, I'd bare shaft tune instead. I had much better luck since this eliminates fletching contact problems. If you are shooting good with a bare shaft, and you aren't with a shaft with fletchings, you have fletching contact. It just seems to fix a bunch of problems doing it the bare shaft way.

It basically works the exact same as paper tuning, but instead of shooting a fletched arrow through paper, you shoot an unfletched arrow at your target. If it's not sticking straight out of the target, you move things around in SMALL increments until you get it right.

Just my $0.02! Good luck!
