MGM Mirage, and every other casino except Harrah's/Rio/Caesars/etc., will tell you up front (how many hours of play) * (how much average bet) = what comps. Harrah's will invariably duck the question, merely saying, "It's based on your play." Harrah's views table games as a necessary evil and caters primarily to slot players. And while I have experienced good comps at some Harrah's properties on some occasions (mainly when dealing with hosts), on the average their table game comps aren't competitive.
