But if you "fly", you can't review? If yes, what's the problem? Because you can read it twice or more. And if no, then it's a technique you have to do it .
By the way, no information will be lost if you photoread......... 
I use the slight vertical mark a lot, because I don't have to read very slow, it goes really quick. It's like superreading/skittering. The first and last sentences are (most of the time) very important. And I skip the examples.
Later, if I think it will help me in the future, I do some mindmapping so I can review in a short period of time. Mindmapping is a great thing to do, I use it all the time.
I use the system of PR for everything. I like it very much. For activating study material I use also RapidReading and dreaming.
I hope this helps you,
Jascha
