If your nock point is below square, it means either your tiller is off or your cam timing is off or operator error. I usually suspect tiller and operator error.

Measure from the string to where the limbs join the riser on each end of the riser. That is measuring tiller. The measurments should be the same distance for a basic tune job. Make adjustments with the limb bolts to get them equal.

And remember that paper testing is usually as much a test of your shooting form as it is of bow tune. There is an element of skill involved. If you drop your bow arm, heel the grip, torque the bow or a hundred other shooting mistakes, you' re never going to get a good tear in paper. New shooters will make a hundred different mistakes while learning.

At this stage in your development, I' d say you' d be better served by forgetting about poking holes in paper and try tuning broadheads and field points for same point of impact.
