If you flipped a switch in the back of your brain, you could watch a second go by like the frames of a movie. Once you figured out what would be happening ten frames later, you could take whatever steps you needed to turn the situation to your advantage. All at a subconscious level. In battle, you couldn't count on anyone who didn't understand how to break down time.
