I've had the course for about a week now. My accuracy in my general playing has improved already. Going through the exercises pretty much eats up all my daily practice time. I'll need to get faster or began to alternate different parts of the warm ups to have time to work on BU.
I was supprised at how much pumping up the old Metronome fifteen points at a time helped after I picked up the pieces and my fingers began to catch up.
