If you typed what you wrote and are able to regular read the post yourself, you shouldn't have any real difficulty using photoreading.
As a note page 30 of the book explains the technique that led to Pauls Skills as a photoreader was a way for dyslexics to overcome their reading handicap... IE. the method used for focus. Start your course by reading page 30 of the photoreading book I think you'll be pleasantly surprised.
Most of all I suggest you heed Pauls key advise "have fun with it". It does work, takes some longer than others but hey we're all individuals. 
Good luck
