I would set the bow at an even tiller and nock the arrow at 90degrees to the bowstring.

The windage for the rest will be correct when the arrow all hit the same vertical line at all distances.

I would predict the rest would be about 1/8" to the outside of the centerline of the bow for a fingershooter to shoot the narrowest groups.

Correct spine arrows will hit the same verical line at all distances and incorrect spine arrow will not.

Good luck tuning!

Good luck hunting! >>>------------>
