For me I personally have stopped using the paper tuning method. Especially after doing a good bit of reading on this forum and setting up several bows this past season. Reason is that paper tuning will only get you close. Here is how I set up a bow.(Assuming you are using a release aid)
1. Set your nock set above an arrow squared to the string.
2. Adjust you rest so that the point of the arrow is in line with the string and the center line of the limbs.
3. Sight in your bow (start close if you're unfamiliar with it)
4. Then using your 20 yd pin shoot at 10, 15, 20, 25, 30 yds if space is limited. If not shoot at 10, 20, 30 40....
Your arrows should fall in a verticle line. (see tuning using walk back method for adjusting your rest)
5. Next and last - shoot your broadheads and your fieldtips. Both should be hitting the same point of impact. If not you will need to adjust your nock set or rest accordingly.

Once you are done with this and your BHs and FTs are hitting the same spot it is possible that if you go back and check on paper - you may not be getting a 'perfect' hole. But who cares. If you do your part, you will hit what you are shooting at.
