I had my bows shooting right down the middle out to 20 yards, but then they broke Weak between 20 and 30.
Not a poke at the OP, but it just blows my mind that people who talk about taking hunting shots from 35-100 yards will check something as important as arrow flight at 35-100 inches.... and call it good.
I start at about 3'(disclaimer, I always use a stiff shaft) and I'll get the tear as close as I can. Then I'll move back to 3 yards, and then about 5-6 yards. When I can get good round holes at all three distances, I am 99% sure that once I fletch the shafts I will have very little if any adjustments to make while BH tuning.
If I get a funky tear after fletching, I'll know there is a contact issue.
If your shaft is weak enough to flex at the release, you'll need to be able to recognize that in the tear. If you look close enough you can see where the point enters the paper. If that entry point is somewhere in the middle of the tear, that's just flex that you're seeing.
