We all know that casino comps and offers and free play promotions are linked to your daily theoretical -- meaning how much you bet, and how much the casino expects they will win from your bets.

But does the casino have your daily theoretical correct?

Earlier today I was on the phone with my host at Caesars and I was complaining about the big drop (by about 50%) in offers I received for January and February 2015.

My host explained that my daily theoretical dropped dramatically and while looking at my play history on the phone my host mentioned in particular my visit to Caesars Palace on July 19 when I "bought in" to a game of roulette for only $100 (one hundred dollars) and played just 20 minutes with a $48 loss.

"That really killed your daily theoretical" my host informed me. "That small amount of play for one day actually cut your daily theo in half."

But -- there's a problem. I did not play roulette at Caesars Palace with a $100 buy in. Nor did I lose $48 over a 20 minute period. You see -- I wasn't in Vegas at all on July 19 and so I never played roulette. (I can't remember the last time I played roulette but I think it was about ten years ago.)

That's when my host realized that somehow another player's "play" found it's way onto my record and I was being penalized for the error.

My host is now going to the marketing department to find out how to "undo" the error. But my host also said this could be a big problem. I will keep you posted.

After we found that error, we went through all of my other visits for the year, and noted that they all appeared to be in my normal range of play. But as my host pointed out JUST ONE visit with low play literally killed my "daily theo" and cut my offers by about one-half.
