At this point, this does look pretty much stable. Though NE2 is really elastic.
But if what we're at now is kind of like the baseline of the race, it means that Hillary definitely has potential to grow whenever Trump makes a gaffe or does something stupid. So +10 still isn't out of the question. In fact, I'm still confident we could add a few points to this number thanks to her organizational advantage. So I'd say +12 still isn't completely unrealistic either if she has a hugely successful debate performance and more goes wrong for Trump.
