Time Turning and Age (was Re: Hermione's Summer)

This post is likely to be a bit long, but I thought I would try to 
work out how much age Hermione would have gained if she aged one hour 
for every hour lived while using the time-turner.
There are six hour long lessons in a day. The six original subjects; 
potions, DADA, transfiguration, charms, herbology and history of 
magic, will have been figured into everyone's timetable. I assume 
flying has been dropped by this point. The new subjects are; 
divination, ancient runes, arithmancy, muggle studies and care of 
magical creatures. The students seem to do two of these, but Hermione 
did all of them. That makes three more subjects than anyone else.
Assuming each subject gets equal time there are roughly five hours a 
week devoted to each subject.
So Hermione is doing 15 hours a week more than anyone else, 5 in each 
subject. Only she drops divination two thirds of the way through the 
term making that 10 in each week for roughly 17 weeks and 15 in each 
week for roughly 35 weeks. So 170 hours plus 525 hours is 695 hours. 
This makes about 29 days.
I apologise for roughness of the maths, I didn't use a calculator. I 
have also made a few assumptions, such as that Hermione did not use 
the time-turner to get extra preperation time. However I think I am 
fairly close to the time Hermione gained and it hardly seems enough 
to make a big difference to her age. If I have made any big mistakes 
with the maths please tell me.

Khilari - who almost certainly has too much time on her hands.
