Adrian,
When you want to photoread thoses unrelated subjects. After doing the 3 to 1 for the very first book, there is no need to do the 'whole' 3 to 1 proceedure for the nexts one, when you follow on immediately.
Specifically, after closing your eyes and stating your sense of mastery for the first book, mentally prepare for the next book (state your purpose) open your eyes with the tangerine in place, do a quick preview to identify your purpose and what you want out of the book spending less than 3 minutes at this. Then to photoread just turn your eyes slightly up... look at at something that is above your horizonal plane of vision (eg a picture on the wall) close your eyes and state your affirmation feel yourself in photofocus and go again with the photoreading. So the time it takes you to get into state again for the next book would be less than 1 minute.
Just remember the closing with mastery for each book and stating your purpose for the next book... your mind will stay closest to the accelerative learning mode and closing your eyes and stating your affirmations triggers it switch on again and you find yourself in full swing for photoreading the next book in quick succession.
