Sir John Hawkwood

I think Kidwell says something about this in his book, "Instinctive Archery Insights". He says that he cants the bow until the arrow is somewhere between both of his eyes. He says this is necessary to shoot instinctively.

In a way though, even point of aim, gap, string-walking and the like are some what instinctive. I have to sort of guess at distances when I shoot. I see the arrow in my peripheral vision, and I notice its location in relation to the target and loose. At certain distances I don't actively measure the distance, it's sort of instinctual, if it can be called that.
