As someone who has worked in the gambling industry handling VIP programs my whole career, it’s going to come down to how much you turnover. If you’re a seasoned customer the house will have an idea of your theoretical value off of your historical ratings and data (I.e. which games you play have different expected results based on house edge/margins) so if someone with a theoretical loss of 28% per “session” playing slots will be far more valuable than a blackjack regular who the house only has a slight edge on.
Your comps will always be based off your projected loss value. If you got comps for big markers all the sharks would be taking out huge markers, get the comps and then barely play. Trust me, the house does not reward you unless you’re giving them the advantage.
