Mostly the explainations of how memory works. If they put that in the PR book I think alot of people would go "Oh, so that's why it takes so long." Or "That's why I got that initially boost followed by a period of nothing working."
Since there is a special forum for this I don't think LS wants too much of the cat let out of the bag so I won't say too much but I will say that everyone skipping the TRIGGER WORDS or QUESTIONS step is KILLING their Photoreading results.
