Yes. Some will disagree and say that instinct is what they do. This method can remain in its initial mechanical state or in time it may develop into a more automatic response, which may seem like instinctive, but once the eyes are trained in the manor as described by Hill, it remains as part of the shot, even with fast shooting. There are some fine points, just like with any other method, that may seem foreign to most, but it is a very convenient and quick method for developing a versatile target or hunting shot. The trick is to start out very slowly and only increase the speed or fluid development that fits you as an individual. I believe that everyone has their own best tempo at any given time. There is no fundamentalist law that must be followed right from the start, when it comes to shooting tempo, but with the Hill secondary aiming that 'imaginary' aiming point is reached with a bit of subtractional math. You draw in a hook that comes a bit above the target and then slightly comes down to achieve the position of the chosen 'imaginary' aiming position, versus additional math that has one coming from the bottom up or awkwardly extending the bow arm prior to the draw. I hunt the rolling corn barrens of Iowa, my shots tend to be longer than what most tree stand users take, this aiming method can enhance one's effective range by quite a margin. One additional point, in Jerry's book, he goes into detail what 'not' to do with the ring finger.
