I just got my very first copy of the Schlossberg Daily Drills book. The way I'm interpreting the instructions is to pick a few drills from each category I-VIII for each day, and it should only take about 20 minutes to go through all eight categories. Is that correct? I mean, there are some of the exercises where it has an asterisk next to it, and then the notes at the bottom say to transpose that drill into all keys!!! That would take over 10 mins! There's a lot of material in some categories, but then not nearly as much in others. It's a little intimidating to try to find what I need to practice from each group, but I spent about 45 mins going through the book today. I played about 2-3 drills from each category, which I stumbled through really most of them. When I was done, I definately felt like I had a great workout and some things were starting to "fix themselves", but still. How do you guys use this book?
