If you are sure that you have the static center shot set up correctly:

Try turning the arrow nock 120 degrees and see if the tear changes. If it does, turn the nock 120 degrees again and see if the tear changes. If it does, then get another arrow. You cannot paper tune correctly if you are using an arrow that is not spined correctly. By turning the nock you are able to check the spine of the arrow you are using. If it is not spined correctly it will shoot differently because you are essentially moving the stiffer part of the spine from, say, the top to the lower left or lower right and then moving it again. By moving the stiffer part around you get different arrow flight. (One of the things we did in Len's seminar )

If your static centershot is correct and you are using a good arrow:

You can try increasing the draw weight to 68lbs and see what happens. If the tear gets smaller but does not go away increase the draw weight again.

Or you can try moving the rest to the right just a very little (1/32")at a time.

I would try to correct it wit the draw weight first.
