well, I think you have to figure that if a casino is going to offer you $350 for CPA they are sure banking on enough players going way over that $1000 buck amount in order for them to make it worth while to give you $350.
I know for me when I gamble I’m way over that amount. Ya’ll would love me. I’d be a whale.
(not the smartest of them, but I’d easily make you wish you went % rather than CPA)

PS. Here’s a question….If you sign in up at a casino under your own affiliation we’ll they give ya money back….? My guess is probably not, but if so it would be a nice way to discount one’s own gambling……
