Best ways to Seven Stars or "Diamond in a Day" for Caesars properties around the US

Thanks for the update. I believe that your experience pretty much verifies they can't see when you made Diamond, which means that I would probably advise others to BS and just claim they made it before the stay started (but after the reservation was made), but forgot to mention it at check-in. As I said, even if they catch you in the lie, you can always make up BS and say you were confused and thought you had Diamond earlier than you did.

diamond lounge can see when you made Diamond.
overheard the lady at the counter tell the guy in front of me that she sees that he made diamond a week ago
