"SuperReading takes only 5-6 sec."
If that is the case why did you need to spend 10 hours on the book?
"I can answer to those questions simply by refering to the table of contents as alex did."
Then everybody going to school and college only has to look at the table of contents and that's it they are done? I don't think so, learning comes in layers.
"Consider you want to photoread a book with 50 questions in mind, do you need to go through the book 50 times?"
Apply the 80/20 rule. 20 percent of that book contains the crux of the book. Spend 80
percent of your time on the most important information not the fluff of the book.
"P.S. I want to learn photoreading and I am sure its something very useful for me."
That's great but i want to know why it was necessary for you to spend 10 hours on the book if you were superreading 5 to 6 seconds a page.
