Yes, I have the book!!
Why don't you try the 3 day test -
1. Day one - take a brief look of the book and its contents and rapid read one third of it
2. Day two - take a brief look of it and rapid read the second third
3. Day three - take a brief look of it and rapid read the last part

Isn't that the same! Just in three days you managed to read the book. It will be much easier if you know what you are looking for then you can do it much faster.

Of all the steps I don't understand the "photoreading" one! Why is that?
You preview the book(manage to take some notes), then super read it, after that rapid read it. In that case you did "read" the book three times!!!! After that you make the mind map and... voilla!

What is the photoreading for?
