The way I understood it was that Pete was good enough at Photoreading to not need to do that stuff. He probably had practiced the techniques so much that he didn't need those extra steps to help with the activation phase. The questions he was asked probably acted as the activation step for him.
This has happened to me before as well, but not as profoundly as Pete's example, of course.
I went to a bookstore to look for a book on procrastination. I found the one I was looking for but I wasn't sure I wanted to buy it. I sat down with it and Photoread, hoping to get an idea of whether or not I really wanted to buy the book. When I started my postview I got really interested in the material and did an activation right there, no incubation period, nothing but PR and activation. I figure I got through the 200+ page book in about 20-30 minutes. I drove home and made a mind map of the material.
The whole situation struck me as funny since it was a book on procrastination.
