I hear ya Ross. It's like golf in that it's not about making a great shot, it's about making consistent shots. Above advice is sound and best thing is to relax because we all have days where we couldn't hit water standing in a lake! (Well at least I still do.) My advice from experience is to start again at the blind bale about 3 feet away and work on consistent anchoring with holding, without picking a spot on the target. When you can consistently hold an anchor and get a good release, i.e. not collapsing after the hold, then pick a spot which is usually another arrow hole at that distance. Hammer that one spot and when you can, step back one step, hammer it, then step back again so on and so forth. You'll be surprised at how quickly you get back to 10-15 yards. And lastly, don't shoot every single day. Try to, but if you are having an off day, relax, do something else and you'll again be surprised at your shooting when you come back to it. You're only going to frustrate yourself by trying to "force" better shooting.
