Margie:

Just thought I'd throw out some info re: how many hours per day Hermione
might be time-turning:

First, Hermione says, near the end of POA, that she is dropping Muggle
Studies because along with Divination that she already dropped, she will be
able to have a normal schedule.  Second, it is clear that they don't have
the same classes every day of the week.  According to the Lexicon here:

http://www.hp-lexicon.org/hogwarts/classes/hogwarts_academics.html#third

First Years have 7 classes -  Astronomy, Charms, Defense Against the Dark
Arts, Herbology, History of Magic, Potions and Transfiguration.  Third Years
add two or more classes to that same seven classes, choosing from Ancient
Runes, Arithmancy, Care of Magical Creatures, Divination and Muggle Studies
and possibly others.  There are numerous examples that support this, one
that jumps to my mind is when Hermione's book bag is splitting and Ron asks
her why she is carrying a certain book since they don't have that class that
day.

With nine classes as the norm, there is no way that Hermione would be
time-turning four classes a day.

However, if she was also using the time-turner to have adequate time for
homework, four hours a day might be reasonable.  The problem with this is
that time-turning for the purposes of homework would be much more risky than
doing so for classes since the possibility of Hermione running into herself
would be much higher.
