Grade 7-8 time: 196h 25mins, over 51 weeks.
The total time between my Grade 5 and Grade 8 exams was 2 years, 2 weeks and 2 days. The total amount of practice over that time was 400 hours and 10 minutes.
So only 4 hours a week?
On the oboe it took me 500 hours to get from Grade 5 to 6 (though I did want to make absolutely sure before I stepped in the exam room

). I think 6-7 is going to be about 400 hours and 7-8 well, where's that piece of string? I was pretty quick to Grade 5 though (hepled by previous experience) and my current estimate from 0-8 is 2000 hours.
NB - I don't write down timings for every practice session so these are approximate. At the moment I aim for about 7.5 hours a week of practice plus about 4 hours of orchestra and windband.

There are too many variables to really draw many conclusions - depends to some extent on when you decide to take the exam but I guess the thing that stands out for me is that it doesn't really take as much as you may think (certainly not the 10,000 hours that have been mentioned)
Though that refers to research on reaching "Expert" ability. That's some way beyond Grade 8 (as I am rapidly learning!).
