The WHOLE process? About 5 books.. I've prepared/previewed/photoread about 20 so far though.
I thought the first run through the book was 30 minutes for superreading but then you start splitting the book up into smaller pieces for the subsequent 30 minute sections?
So I guess when you are dipping you are 'speed reading', not just regular reading, since you say you only spend 6-8 seconds. Yes? I had been slowing down to regular speeds while dipping.
