no doubt its consistancy, also in 3d, besides repeatability, its knowing the difference between 42 and 44 yards up a hill. a lot of it is just plain form and practice.

i had a semi-pro shooter over last year. i took him out to 72 yds and didn't tell him how far we were from my bag. he picked a spot on top of the target and put 6 arrows in about a 3" group in thering- and this is only after shooting 3 arrows beforehand. he did end up shooting a flyer eventually - it was about 2.5-3" low - that was his flyer. shot a practice round a couple weeks ago with a buddy who came in 9th in the world in the semi pro division. we shot 17 targets. he was 14 up from the pro stakes.

another aquaintance just took 3rd in the world from the pro stakes - adam hayden - and he's about 5'6" tall - shooting i believe a 26" drawlength - so don't let drawlength discourage you.
