Eric it becomes a question of time. How much time do you really want or need to spend with the book?
Would photoreading a book again just prior to your next activation layer make it easier. Yes if the subject is more challenging or new to you. No if you're already have a good degree of knowledge on the subject. Then it wouldn't really make much difference.
There are even occasions when you Photoread a book lots of times before you really start activating it. Simply because your instincts tell you you're not ready to activate it yet.
Ultimately it boils down to your purpose. If you need to know what's in the book now. You'll start activating it after only one photoread.
Of course if you've read some of my post you'll know I do suggest that when you get your textbooks at the beginning of the semester to photoread them everyday for a week or two. Then 2 weeks prior to any exam. Give them another week of photoreading. It probably helps a lot and it sure doesn't hurt.
