I am not sure how to interprete the review.
What I can tell you is that I spent 3 days (about 1-1:30 hrs each day) reading the PhotoReading book; in the following 2 days I was practicing the techniques and on Saturday (that's last Saturday), I tried PhotoReading my first book (on the subject of flying/pilots/planes/air health/security which I borrowed and had no idea about). My friend asked me a few questions and guess what.....not only I got the main concepts correctly but I could answer a question concerning specific details. In total I spent about 1:15-1:30. That's during my first week. I keep practicing. I have nothing to loose.

Good luck
