I'd like to add onto this thread if I may.
What method do you use to ensure your knocking point is in a good starting position? And from there, do most of you paper tune?
Single Cam start Ncok point 1/8 to 1/16 nock high using a bow square, if adjustments are needed from there, they are usually down in 1/32 inch increments.
Paper tuning is a double edged sword. If you have poor or inconsistent form you will drive yourself nuts trying to figure out what is causing the poor tears. Paper tuning is not the end all to beat all, you must group tune(Walk back tune) your bow also out to at least 50 yds to eliminate any erratic flight issues.
