When I was competing in field archery, Bowhunter Freestyle Limited (pin sights, fingers release, 12" max stabilizer length), I could consistently beat "archer's minute of angle" (1" per each 10 yards of distance) size groups, even on the long targets. I'd get quite a few of those teenie little groups on good days, but not consistently from one day to the next.

Shooting Competitive Bowhunter class (same as BHFSL, but without sights) my usual groups were just over archer's minute of angle. With sights, my 60 yard groups averaged just under 5". Without sights, my average 60 yard groups grew to 7". I've got a good gap system.

On the other hand, even though I won my share of tournaments, I regularly got my butt beat.[:-] There are some guys out there that can flat smoke your buns on the target course!
