I am not sure about what the score patterns are but i can tell you that his method is really well organized. However, it is def not for everyone esp if you don't plan on studying for a long period of time. I thought his plan would bog you down, i personally would not dedicate more than 6 weeks to hardcore prep. You could probably pick and choose parts of his method to make it work for ya..but trying to replicate is probably not the best idea!
