I started shooting 3 under on my Bear recurve which made sense to me and I was reasonably accurate, but since then I've become interested in Asiatic shooting thumb draw on the off side which has a totally different sight picture. I had to become instinctive and I've learned that you need to cycle a LOT of arrows to train your brain, and you need to do that at every distance you'll shoot from a variety of positions. I try to move around alot when I shoot and not shoot fixed distances. The other thing I found useful was learning to guess distances accurately. I'll look at a stick when I'm out walking, guess its distance and then pace it out. So much to learn!
