So in a very simple case, would something like a differential equation to which we later add a higher order term qualify?
It seems like if it is to be generally true, iterated refinements of “the same” model are really just a special case.
Sure. In that case, it would say something like “the higher order terms should be small in places where the lower-order equation was already accurate”.
