Do you assume most NM+ are pre-screening rejects?

If the person selling the book seems to have a lot of slabbed books I almost always assume the books must have gone thru pre-screening for 9.8. I know there are a bunch of reasons to sell books raw considering to cost and time it takes to slab a book but it always crosses my head. Do you assume the same thing.

 

And if you did get a batch of rejected books from a pre-screening would you state it in your sales thread or is it no ones business as long as you don't state they are possible 9.8s.

I always do a pre screen for 9.8, my rejects can be looked at a few ways. I can say they are at least a 9.4 or 9.6 which i would state, or if i think it is a hot enough book resubmit for a 9.8. If enough rejects come back i don't think will sell, i put them as gifts to people who win my Ebay auctions.
