That is an amazing display of a highly developed Photoreading skill. However, I can see why LSC wouldn't put this up as a promotional commercial. Their book, at least, doesn't teach this. (I can't speak for the home study course or the seminar because I never took them.) The material presented only teaches you to increase your normal reading speed. The material doesn't teach you to develop skills to the level you describe.

Don't get me wrong, I do think that what you describe is possible with a lot of practice. I just don't agree that these types of experiences are the way to sell or promote Photoreading. If LSC were to create a course or a book that taught people how to do these kinds of feats, then this is the type of experience they should advertise.
