I feel like most here do, practice, practice and you guessed it, a little more practice. Good form and practice equals consistent shooting, as long as your equipment is tuned properly.
The longer I shoot the less I think about distance while aiming. I once considered myself a "Gap shooter", now days I never think of gap. I hold my draw for a couple seconds and concentrate on a small spot on my target. Is my way the best way? Well yes it is for me, and it sounds like you're getting your own aiming system down. The longer you shoot the easier the path to success becomes.
In my opinion, we all shoot instinctive as long as there are no sights on the bow. Really shooting traditional is as simple as being consistent and finding an aiming system that works best for you.
Good luck in the upcoming season, you'll do fine.
