Also the math is not quite right. You get 2 points/$1 rake, so 2,000 points = $1,000 in rake, which is 10% RB when cashed in for $100.
I wouldn't factor in the 600 you have to pay to clear since that, since it is also going towards your next 2,000 points for $100.
I'm not defending the structure or anything, of course I'd love to have 27% RB...just being a nit
