Bernie, gap shooting is where you use the tip of the arrow as a reference: At a certain range, you can place the tip on the target, and the arrow will hit the target; closer, you must hold the tip under the target; further, you must hold the tip over the target. Instinctive shooting is where you focus only on the target, no matter what range, and release, the idea being that it can, with practice, become just like throwing a ball.
