Not to fuel the neurosis, but if the change is really happening at different times for different people, it probably does mean something. I don't think there's any inference you can make about the outcome of your application. But given that we know that Stern updates the application website manually, it must mean that your application was accessed or updated in some form. Of course this doesn't really provide any specific answers, but I would theorize that if we're seeing more and more updates to the application page, there are probably a bunch of notifications coming.
Which we already suspected. Which leaves us in exactly the same place.
But at least we're passing the time.
