There are a LOT of variables in such claims. I can shoot ONE pin to 24 yds with a margin of error of no more than 3" and at that margin of error, if I forget to hold under a tiny bit, I've still got a dead deer. I shoot for HUNTING ACCURACY, even though I do some target archery, all of my shots are with intention of eventually having a deer at the other end of that arrow. Certainly we all have different drives, skills, abilities, and goals, which explains part of why we may have many different set-ups.
