Wgc3rd,
Both superread/dip and rapid reading are forms of activation.
The difference between the two is that rapid reading is used when you want the ultimate in comprehension. You go through the entire text.
Superread/dip is similar in that you only go through selected text that interests or catch's your attention so to speak. (Remeber how they describe Superman hovering above the earth and dipping when something catch's his interest?)
The time limitation is mentioned because activation is best done in 30 minute intervals. If you want, after 30 minutes, break for a bit, then continue activation if you have not completed the entire book.
PR is a system. No, more importantly, it's a Flexible system. Find your style of PR that works Best for you and stick with it.
Good luck.
