Exactly what Rev said. I don't hold much salt to paper tuning either. I visually line everything up square then sight in at 20 yds. Then I use the walk back method to tune the rest. Next I broadhead tune so my field tips and BHs are hitting the same POI.
I started this method several years ago and have been shooting better than I have all my life. And I've been shooting bows for over 50 years.
