Being NP's, we're pretty good at responding "as things happen" anyways, so it's OK if things don't go EXACTLY according to plan. Most of my constructs cover the basics of "what will probably happen."
It's like drawing a big circle and then saying, "I know the dart is going to land SOMEWHERE within this cirlce". Rarely does it land outside of the circle and, when it does, that's OK too because we'll just adjust and respond accordingly - and then go back and tweak the construct as needed.
There are those rare times where the dart lands WAY out of the circle though and I'm kind of "stumped". We're good at handling curve balls, but sometimes the pitcher will surprise you and throw right at your head.
