DaveC, you are right on. The group is the size circle all of your arrows would fit in.

5 arrows? Well, I'd probably be around a 4" circle without taking a few warmup shots.

I don't know the formal definition. The way I define it is like this:

If you shoot 5 arrows at the same spot and draw a perfect circle around all 5 arrows, what would the diameter of that circle be?

Cool, then I'm on the same page.
My last group yesterday was 2.5" at 30 yards, but only 4 arrows.

I would like for this to be under 2" and will continue to work on things until it does. My form, my release, my bow, my arrows- never ending quest for POA shots.

My groups at 20 yards are usually very good, at 30 yards I can put 4/5 inside 2", but it always seems like one out of five is off by a little bit

Hell, I'm lucky if I hit the target![8D]

I shoot enough during the offseason, almost once a week, for sure everyother weekthat I knowI canshoot a 4" group year around. But through the spring and summer when I step up my shooting practice to once or twice a dayI know I shrink my groups below 2". Iselected4" on the poll,because that is what I know I can do year around.

This is 3 arrows at 30 yards just before opening day of last season!

I can keep them within a 4" circle at 30 yds without too much trouble during the summer and fall. I've slacked off a little bit on my shooting right now however, so I don't know what they are like currently.

I'll be honest and tell you I take spells. On the average my group size at 30 yards is more like 3"-4", sometimes 2". I can do the same at 40 most times, sometimes not. For a guy who is about to turn 52, weighs around 150 lbs. but shoots at 67 lbs., shoots a right handed bow with a left dominant eye, has to shoot with one eye closed, and can't decide whether to shoot with his glasses on or off[&:]...I don't think thats too bad.
