The dash for cash points are not poker owned points. If you look at the dash page it shows you the value of $1 in dash points. And once you get to that level you can redeem those dash points for $1. When you first enter it for the week you gain 100dash points for the 100 pokerowned points you used to enter. So basically if noone rebuyed 100dash points would be equal to 100 pokerowned points and the amount needed to redeem $1 would be around 500, but as people rebuy it lowers the value of dash points in relation to poker owned points meaning the amount of points needed to redeem rises.
