This brings up a question I have about whether I'm doing something correctly or thinking about it the right way. I have always set center shot based on the center of that curve on the shelf to get started. I then go to paper tuning. BUT, I have never really paid any attention to my left and right tears so long as they're not ridiculous, only vertical tears. I adjustthe vertical tear outonly. This way I know my vertical is close. I then go to walk back tuning to set my horizontal adjustment.

Of course I do all of this knowing that I have the correct spined arrow. I've done this in the past and have gotten very good field point and broadhead groups this way.
