Am I correct in saying that there is no calculation to determine reward credits? I know tier credits are $5 = 1 point for slots, but what I read reward credits are not calculated the same way. I'm just trying to figure out if I earn the 1k tier in a day, how many reward credits is a boy to get along with it? I've ever paid much attention, all I know is that they didn't add up fast enough haha

Thanks, I'm a noob!
