When I started shooting archery I shot the same way you are describing. One fluid draw with no stop to anchor. I did exactly as you said and did all my aiming before I ever drew the bow back. I practiced every day and became very effective at this. On my good days I could really stack some arrows.
Now the downfall, I found if my concentration was lacking at the very least my accuracy and consistency would go down the tubes. I lost all of my confidence and my accuracy plummeted to the point of where I would not even attempt to take a shot at an animal with my bow. This was after a full year of shooting by the way and after successful harvests as well.
So I went to split vision/gap shooting and found that even on my worst days I could be consistent enough to put the arrow where it needed to be. After awhile gapping has become subconscious and it is now turned full circle to where I don't even think about aiming much anymore. To each his own I'd say. Good luck and good shooting! SS
