If you want to use photoreading you use it everyday on all your reading material. So everybook you photoread. If you want to gain a sense of competence. Photoread 3 to 10 books a day and fully activate at least one book per week.
Mind mapping is particularly useful in the early days of photoreading (still is later but becomes more optional depending on what you need to know). Mind mapping brings the other senses into play with reading and gives you more focus. While it may 'seem' difficult at first by sticking with it you find your mind clicks faster on the questions during superreading and dipping. So while learning I recommend mind map every book.
