This is why I have auto-update turned off. I also wonder if that is how UIDs and other such things can seem to be a bit off at times. I may refresh five or six times a bread, depending on how active I am. In theory, those of us who are very intermittent with our refreshes will only be very fleeting in the UID count. I am not sure what the decay rate on that is, though.
