Ah—your body has all the muscle memory, so as long as I could focus and tell them that they were basically stuck with me, it was just a matter of calculating the appropriate angles and trajectories for maximum efficiency and avoiding movements that might cause problems. Essentially, I deduced that being able to theoretically conceptualize it in this situation actually sufficiently translated to a basic amount of proficiency based on the fact that your body was already ingrained with the necessary and appropriate responses.
