Focus is the active word here. Shooting a bow, instinctively or some other method requires a lot of focus. Denny Sturgis Jr. wrote a great article in TBM not to long ago about shot sequence and reasons we miss. Regardless of how quickly, or slowly the shot happens, the sequence must be present. Think of shooting a rifle. Do you throw up and pull the trigger before you've had time to set the buttstock, aim, then fire??? Not if you want to hit anything. Shooting a bow is no different. Regardless of what the sequence is it must be present and non negotiable. A solid sequence can be performed as quickly or slowly as a hunting situation may require. Check out Terry Greens videos, his shot is what many people would consider fast, but the SEQUENCE is flawless EVERY TIME. Rod Jenkins, who I have studied a lot, shoots very slowly and calculated, BUT THE SEQUENCE IS FLAWLESS.
Moving back to focus, focusing intensely on a given spot and intensely on your form simultaneously is a vey hard thing to do. If the form is ingrained in the subconscious, this frees up a ton of brain power to focus on "the spot". I am no world champion, and certainly not as good a bow shot as i would like to be, just my opinions, mostly borrowed from folks who can shoot the lights out.
Best of luck
