Money -- your daily average is not your daily coin in average, it's your daily THEO (theoretical loss to the casino). And yes, if you have no play days or trips it is definitely going to dilute your average. There's really nothing difficult about this. We come back to the point that you like to hear yourself talk. Make sense of it or not. I'll try to help those that want to be helped, but you are clueless.
Ledhead -- in one of my posts I stated that you used to be able to book JUST a room comp and if you didn't use your card for anything (to play or access your comps) you would not be tripped. However, that is not the case anymore.
Lisa -- I don't believe that to be true in Harrah's system. They call it something different now (market value worth, or some such nonsense), but it's still your average daily theoretical loss to the casino that they're looking at for comps.
