I disagree repetition becomes instinct

In Kung Fu I practiced a lot of techniques over and over again started off struggling as time went by I got more proficient then before you know it its becomes reflex someone throws a punch your block it and think wow how did I block that or something drops off the side and you catch it . So the repeated training makes you sharp. I expect this brain training will do the same in time the exercises will become instinct or a reflex and you will be come sharper.
