If it was me I would throw the paper away and use the walk back method. I would think you could do a search and find some info on it. The nutshell version is you take one pin on your bow and sight it in at 10 yards, then using the same pin shoot at 30 yards, bear in mind it will shoot low. Look at the point of impact to see if it is right or left of the bull you were shooting at 10 yards. If the arrow hits to the left, move the rest to the right and vice versa, a little at a time!!!! If it is off move the rest and resight at 10 yards then "walk back" and using the same pin shoot at 30. Keep doing this till your arrows hit in the same vertical plane. You can stretch it out to 40 or 50 once you get it close at 30 to fine tune it. I tried the paper method and about pulled my hair out. Hope this helps. K.B.
