My question addresses a concern of mine regarding Paul's comment about "overpreviewing" the book before PRing it. He says that if we preview it too much, it will shut down the internal processing of it. I know that previewing it in order to PR it and have read it previously are not the same thing, so I just want to ask if having read it previously has any impact in the PR/DL procedure (i.e. interferes in the inner mind's processing task).
