Wondering they come up with some of these bonus clearing estimates, specifically ones that look like this:
Paradise Poker:
1/2 5.61 7.63(shorthanded)
2/4 3.89 5.17(shorthanded)

why would the bonus clear at a slower rate playing 2/4 vs. 1/2? they say you have to play 100 raked hands for each $10 in bonus money, so why would it matter whether you played 1/2 or 2/4??

thanks
