Hi timastyle,
I am in no way an expert, and my comment probably isn't all that helpful, but I found that I wasn't smart enough to get things figured out by reading the book, so I got rid of it and bought the DVD's, which have really helped me get a grasp on what they are teaching. I have yet to see if I can actually make it work, however. (BTW, I'm not affiliated with any of those guys and am in no way trying to make a plug for buying the DVD's).
