Instinctive shooting takes thousands and thousands of arrows and everyday type practice. It is such a thing, but it happens without you even knowing it. Just about everybody uses something as reference. I used my arrow tip for the longest, but obviously the tip isn’t pointing at full draw where your arrow will hit. Once you get a feel for where your arrow hits in relation to the point, then you begin to only see the point in your peripheral and you’ll solely be focused on the target. Later that can translate into full on instinctive, but no body just picks up a bow as a newbie and hits where their eyes are looking.
