Carl, An observation,
You seem to be spending a lot of time looking for other people to do the activation for you. You really need to get down and do it yourself.
Do 6 X 30 minute activation passes on a book if required. In those three hours you've covered more ground than a regular reader (they would average 12 hours) and textbooks usually require 25 to 50 hours so look at 5 to 15 hours for fully activating it.
Correct your technique (borrowed genius does not belong to the photoreading steps it is something you can do at another to build your skills.)
Prepare - tangerine technique.
Preview - limit it 3 to 5 minutes on a book 10 to 15 minutes a textbook
Enter ALS, affirm, tangerine and photoread.
Activation - tangerine and allow your eyes to see the whole line as you scan down the page. If your peripheral vision is weak use skittering, a zig zag type scan might work better for you so experiement. Check the book it explains alternate ways to activate.
During activation your focus should be closer normal. Regular read the passages that catch your eyes. Look for meaning, read words in goups (phrases).
Notice your body signals, visual - the text might sparkle, jump out, look bolder, hearing you might hear yourself say key words on the page or your mind say stop read this. Physically your body might tingle, twitch, itch when you are scanning over information that you want to know consciously. These are only a few of the mulitudes of ways your body/mind connection is telling you to dip. Practice following them and experiencing the results.
Stay with it till it gels means; do one 20 to 30 minute activation pass, take a 5 minute break, do a quick review of the information you brought to consciousness and decide if you want to know more. If you do, do another 20 to 30 minute activation pass. Keep repeating (with breaks and the breaks can be overnight) until you reach the point that you are satisified that you understand the material. It seems to me that you would have difficulty with this material even with regular reading, no doubt that's why you turned to photoreading.
Work in layers build your learning in layers. The foundation takes the most effort. Once the foundation has been laid you will find successive learning becomes easier.
