I think this is much more of a spectrum than you're implying. And perhaps more than I've implied above.
The reality is that the vast majority of real-life situations are hybrids[0]---some things are constant, others are new. The math we do changes, but math doesn't change. Boyd's OODA period may have been shorter than that of enemy combatants, but he still had to go to training. What is training if not pre-compiled thought? And importantly: in fluid environments where novel things are likely to arise, having a solid grasp on things that are "settled" makes it easier to integrate new phenomena.
