Hi,
For me, the more I route it through the grey matter, the worse it is. As soon as I come to full draw, with a good anchor, the arrow is gone. No measuring, no looking at anything, except the target... including until the arrow hits. My shooting is truly instintive. To me, it's like throwing a baseball... there is no way to measure. Look at the glove, and subconsciously, let your instincts do the rest. There is more than one way to skin a cat, and whatever works for you!!
