If you are superreading without a purpose or mind probing questions it's going to be easy to miss the information.
You may need to try skittering instead.
Also give yourself more time. Even with two months learning with the book alone you probably spent less time actually applying the system than they do in a live seminar. So go easy on yourself.
The hardest part is playing with it. We always want results in the now. It's odd that I happen to see your post right now because I am just in the process of posting my latest article to my blog and it relates to the subject of learning PhotoReading and making it your own.
