If you're truly instinctive, your mind & hand will adjust through practice. You've got one thing going for you; consistency!
One way to see just how instinctive you are shooting is to shoot, from odd distances, during the dark of the moon at a target illuminated by a flashlight, downrange, and you cannot see the point of your arrow when drawn. If you totally blow-it, you're probably more of an instinctive-gap shooter. That's good to know!
Insofar as tuning goes, it's always beneficial to eliminate problems that come from the "toos": too much or too little in the way of spine, nock point, brace height, etc.
