Also, it is pretty clear she do not step away because she sees herself (It is not even her iniciative to move away). Albeit, I could careless, it is nitpick.
Also, she is not waiting Dumbledore at all. The kids often bypass any restriction and in fact, she was already using time travel for her own safe and the trio was hiding behind pumpkins because they could not be seen by the addults (Dumbledore included), so wating for his go-ahead is just non sense.
Another thing, being a teen-book (or movie)does not make it impervious to criticism. I find no such flaws in Alice in Wonderlands.
Finally, I really do not care about the physics thing. It is as I said a plot devide like most magical stuff, the consequence of its use is never explored. This is a negative for the book and JBI have every right to question this, but I do not care and said nothing about it. In fact in my opinion the most strange thing is that she may come back time and study extra 8 hours, but her body would be tired in the same manner, so she would eventually have a "time travel lag", with excessive use, be much more tired than the other kids, just like we do when instead of sleeping we spend the night studying. It was not that effective, but since the movie does not explain how many times she used it, it is a bit pointless to consider the effects.
