15:45 is about right.
In the technical sections you may have to slip the clutch a bit if you need to bring the front wheel up high, but this is a good way of learning control.
It also helps on steep inclines to save changing down and loosing all momentum.

Any good off road school should explain this better and have some rocks or hills for you to practice on.
