Mark,
I'm sorry you're having a hard time with it. I asked before what kind of texts you are reading, which is important.
For example, many of the philosophy texts I read makes it heard to SR+D, because it's a dense text; logic papers are almost anti-PR, because there really isn't that much irrelevant text to begin with - logicians try to stay succinct as possible.
There are still exceptions like Descartes, where half the text is simply giving examples or reiterating previous points; here SR+D works well.
I find that the easiest books to SR+Dip are "Idiot's Guide to" books. I really like the series of books since they try to explain things in easier terms, but if you SR+Dip it, you can get done if much less time. I read a book in a similar format using SR+D and took in all the information from start to finish in less than 45 minutes; as a 200+ page book, it's not too bad.
"Do I have 100% retention of everything I rapid read? Of course not but I sure can talk your ear off about what's in the book. After Photoreading I could probably meditate on it then answer t/f or multiple choice questions in the neighborhood of 70%. Which is better?"
Mark, try a system that my friend and I devised. You do one pass of PRing, then a couple photoflip sessions, then just rapid read as possible without going back. Keep in mind you will do some SR+Dip sessions later as this will relax your "I missed a lot" feeling. Then just run a couple SR+Dip sections. If you are allocating your time correctly you should come out way ahead.
I studied Evelyn Woods Speedreading and PRing, so using each system separately on two similar books (same author same topic) the PRing was done faster and had better retention than a one-pass speedread.
