Remember "INCUBATION." We've all watched movies that we've seen before but this time around we see things we didn't see before. Of course "we saw" them but this time we were in a place to actually be able to notice and use what we saw. There is a reason PR makes you go thru the books multiple times. Each time we read actively and then rest we set the stage to understand more the next time around. Sure beats reading one time thru with total "comprehension." It really beats the other way of reading. Just give it time.
