Anyone have any theories on why the tier credit earning in Detroit is so much worse than Vegas. (It's 1 tier credit per base point in Detroit, but 10 tier credits per base point in Vegas). I realize the competitive casino landscape is quite a bit different, but a 90% difference seems pretty severe. It seems unlikely that the slots are that much looser in Detroit (but perhaps they are?). I can perhaps understand adjusting the cash back portion, but why make it 10x harder to reach an elite level?
