Ked,
Did you form those mind probing questions before or after you activated the text?
Because if you had them before you had the foundation of a mind map. With each pass you would have been extending the branches with the answers. When you dipped. Two or three key words from the text can do the trick to help you trigger recall.
Also which such complext text I would mind map as I go. Sort term memory, the 7 plus or minus 2 bits of information just isn't enough room and I would forget more making it feel like I only got the edges of the information.
True it does slow down the activation. But in the end it's pads out the information more.
Also after a preview or post view of the whole book, when I know I'm going to want more detail I'd go straight into rapid read with mind mapping pens in hand.
Of course if you had to do a whole book. Remeober to PhotoRead at the very least the chapter that you're activating again.
Subjects where you feel bogged down and are missing information might mean your mind needs mull over it some more. PhotoReading again can work like re-reading a passage 5 or six time.
Even in traditional reading 10 pages can take 3 hours to get the analytical level of information. The reading speed is about 45 - 90 per minute (analytical reading speed). Which is 74-minutes (45 wpm for text consisting of 330 words per page.), just reading it once if they have to read it again to improve their level of comprehension...
All books are not equal and it is still worthwhiil applying the system to that text. Lawyers have successfully used it wo why shouldn't you?
