What do you expect from more advanced guys when the discussion is about "All Cows Eat Grass"? I can appreciate the want/need to learn how to read, and this book can be helpful. I said before and I'll say it again, IMHO I don't think knowing how to read is necessary for this book. You play the exercises with just the roots. Then you have exercises adding the 5th etc. I believe it's more important to know where the chord tones are in relation to each other on the neck and being able to play them in time.
Sorry for the rant, but I'm really not getting anything out of this thread when the subject matter is learning the notes on the staff.
