What is a tolerable income (in %) of the total deposited amount the players have made at any given casino (over 1 year of time)? And with tolerable I mean you keep promoting them or giving them the same exposure on your websites and not replacing them for another casino.

Just average players. No freespin-hunters, huge winners or anything like that. People who look for the best casinos to play at.

I know that deposited amount is not the metric to watch but gross revenue. But over big samples of data you still can see patterns in deposited amounts vs income. It can vary alot between casinos.
