Interesting situation on the static and settling in before comparison. And, since cable comparisons typically are rather difficult to make on a blind A-B basis I think I'd agree that multi-day listening allows one to slowly get a feel for the overall sound or changes. (I've got a huge pocketful of money for the blowhards who think they can guess direct A-B comparisons when truly BLIND.)
I used to think blind A-B was the only way but now I'm starting to realize that for extremely subtle differences between high end components you really need lots of time to hear everything and to be able to make long-term comparisons.
