I suffered for a long time. I read many things on the subject. One video ( Push Release ) helped me more than anything. The technique decribed in the video didn't help, but it got me thinking about how I aimed.
I tried for a long time to be a pure "instinctive" shooter. I found it didn't work for me at all. I became the "bad" kind of snap shooter. So I threw all those techniques out and tried to gap shoot. I still couldn't come to my anchor point. So I would reach anchor and have my friend count then I would release. Arrows still went everywhere.
The past six months have been very productive. I dropped down in bow weight a little. I restricted my shooting to 10yrds, and I only shot 3 arrows per round. While I was doing this ( and after I saw the Push Release ) I got to thinking. Even though I thought I threw everything about instinctive shooting out, I realized I was still doing one thing that held me back. I was aiming during the draw. This caused my premature release. It was my "trigger".
So I compared shooting a bow to shooting a rifle. You don't aim a rifle til you get it up in shooting position and have your finger on the trigger. So told myself not to aim my bow until I was at full draw with my finger on my tooth. Only then do line up the shot.
I am back to my heavier bow with much improved results. Didn't do any blank bale shooting at all, just switched to a lighter bow for a couple months, cut my distance in half, and most importantly, told myself not to "aim" during the draw.
Years of frustration are beginning to end because I found my trigger. Everyone's trigger is different, and figuring out what your trigger is is the most important step. If you aim during the draw, and you are familiar with rifle shooting, this method may help. Pretend your bow is a rifle. I have to give credit to the Push Release DVD for this, I didn't like the technique described in it, but it helped me identify my trigger and come up with my own solution.
I still don't hold long, probably less than two seconds if I had to guess, but my arrows are starting to group much better.
