Okay, so you made me go home and pull out my copy of Go Rin no Sho. In the Book of Water, Musashi talks about To Hit the Enemy "In One Timing", which is sort of like "Just fucking hit him." He also talks about The "Abdomen Timing of Two":

When you attack and the enemy quickly retreats, as you see him tense you must feint a cut. Then, as he relaxes, follow up and hit him.

That's what I'm talking about. Uh, I think.
