The PR step seems for me to be building comprehension or "layering" that you guys have been speaking of. That is to say that when you go back through to super read/dip and/or rapid read, multiple photoreading sessions (such as on p77 of the book) increase familiarity with the book. Try the test on p77. I tend to just rapid read after the PR step, but I still whizz through the book!
