I'm going to assume that you want more out of your text books than you are getting from the "caveman"
technique. When you consider how much time it would take to read the text books twice (to get more out of them). Look at the activation part of photoreading as one reading of the textbook. The time where you dig out the really important information from the book and create a mind map. Once you've done that you can add a rapid read... this will be faster than your "caveman" technique because now you fly over the stuff you've already mind mapped.
Sure it seems like your spending more time with the book initally but in truth you are more actively learning from the book. The reason it seems like more time is because you've added a learning stage to get more out of the book one that you would normally bypass when reading with the regular method.
Let us know how you're doing and specifically what you're doing so that we can give you advise if you need it.
