I prefer to believe that the positive affirmations after photoreading as a way of letting the information from the book 'sink in' to my brain. It reinforces the incubation process.
BTW, My supereading skittering dipping skills are improving. I think that by allowing the subconscious to lead the conscious mind through the pages helps a lot. Cuts my reading time by 75%.
And talk about direct learning. After photoreading 2 books on basketball I found myself better at scoring. It didn't happened straight away when I stepped on the court but rather improving at a tremendous rate.
Lastly, I believe that PhotoReading works for everyone as long as they have faith in themselves and the system. Of course, not putting too much pressure on yourself and keep an open mind helps too. I just started for less that 1 month and I have started to see results although there is not much of a spontaneous activation yet but I hope I could achieve that in the near future.
