I would not think there be one.
I just picked up a book I had only photoread, maybe a year ago for I had need for the info a few days ago.
I immediately knew to only look again at the back 50 pages after quickly leafing it, like for 15 seconds. I photoread that last chapter and dipped two or three pages and then put it back away as I knew it.
The book is technical and I needed a higher grade work to keep moving forward.
