I disagree, speed of execution _IS_ the thing - at least compared to your opponent. Boyd's way of thinking didn't have you doing the loop as A->B->C->D->E faster than your opponent, if dont properly, it has you in the orientation phase, recognize the outcome without having to think about it, that is, skipping the Decide phase. If you know how to act when presented with a visible picture you can work faster than someone who has to ponder it first.
Think a baseball game. The kids are taught to recognize where the "play" is. That is, if they know that the "out" comes at 2nd base, they are prepared to throw the ball there if they get it. If, once they get the ball, they have to think about where to throw it, the runner can get 3-4 strides farther along and might beat the throw.
