Do what works best for you. Don't give the photoreading system rules it doesn't have. If you haven't got the knack yet of holding the blip page and find photoreading on the computer easier then uses the e-book version.
If you want to maintain consistancy open 5 or more of the chapters and photoread them in one sitting. Nothing wrong with photoreading the whole lot one after the other. Think of it like handling multiple web pages. Works just as well.
