What I think you are doing is moving from conscious behavior to habit - which is exactly what you want to do. In sports I believe practice is the way they do that. As the brain develops the control it allows you to slowly back off on concentration. Much like learning to drive. First time you are thinking about push the accelerator, turn the wheel, etc. with 100 percent concentration. In a year you are driving, talking to the person next to you and listening to the radio. You want to get to the point where you are not thinking about the tongue. Try some exercises where you have to focus on fingering. That way your mind is working on which valve to push and not the tongue. Just a thought.
