If your are shooting quarter size grouping's at 20yrds, 54/60 times. I think its time to sign up for some tournaments. I have the ball method. Golfball at 20-30yrds. baseball at 40yrds, and softball at 50. How I do this, I take rolls of vinyl(I own my own vinyl lettering company) I cut out circles these sizes with scissors and put on my targets. I practice with 3 arrows, I put all 3 in the circle I move to the next target. I do this repeatedly, then I randomly choose.

But as mentioned, usually you have an idea of what you did out of place that made the arrow miss. This is assuming the bow is set-up perfectly for you. Great shooting even if it is 20yards!!

I like the video camera idea as well, I bet that would help a ton.

Any time you miss your shot (no matter what size your target is) you should think about what you did to miss. The key to being a great shot at a known distance is to do everything exactly the same why every time. Once you start getting close to that you will develop a feel for your shot and as Bob said, you will know whatyou did wrong before the arrow hits the target. I like one arrow practice rounds, but the best practice I have found for developing that "feel" is blind bail shooting. Give that a try, it will really make you focus on the feel of your draw, anchor, and release. It also does wonders for those that are having any kind of target panic.

For the most part I think this is a very good way to shoot. The only comment I would make is that for beginners, repetition (as long as its correct repetition) probably would help more than single shot practice. Once the basic form and muscle memory is down part, a “seasoned” shooter can probably eke out more from single shot practice.

On a separate but related topic, I think analyzing the miss when it occurs on a real animal is HIGHLY overlooked in bowhunting. Too many people attribute missing to just being part of the game, but I think that given just a little bit more effort, one can reduce their misses on game down to very low levels.

Although I do not shoot 1 arrow per group, I do analyze every shot. I have been shooting for long enough that I can usually "call my shot". What I mean is as the arrow leaves the bow I can generally tell whether it is going to be on, right, left, whatever. This is why I like practicing 90% of the time at 50 and 60 yards. It is truly amazing how much different it is shooting at 50 compared to 40 and 60 compared to 50. The difficulty, and resulting group sizes, are not linearly related. It is definitely an exponential curve.

I can say that 99% of my errant shots are due to a bad release or dropping my bow arm at release. The first is the one where I am cussing before the arrow gets to the target
