An average group for me at 85 yards is about 1 foot across. That is as far as I practice, and only practice that distance maybe 1 out of 5 shooting sessions. Note that is an average, there are some real fliers at that range for me. I have to bust out the big bag target not to lose arrows. Not nearly good enough to shoot at animals. Yet I practice it because like others said, you really have to focus on form. About 75 yards seems to be a magical distance for me where form breakdown becomes magnified very very quickly. I don't practice much this time of year but starting in the early summer I ramp it up to the point a couple months before hunting season I shoot about every day. Some days just 1-3 arrows, some days I'll shoot for an hour. Much prefer shots under 40, but the farthest I will shoot an animal is 50, maybe, maybeee 60 if everything was absolutely perfect. I can keep 99% of groups under 6" at that range even without a lot of practice, and the slightest miscues aren't lost arrows on my 18:1.
