Because they are playing a different game than you. You have to judge how bad the paytable is relative to the full pay pay table for the specific variant you're playing E.g. full pay bonus poker (99.17%) is 8/5 (full house/flush.) For double bonus, the comparable game with 99.11% payback version is 9/7/5 (full house/flush/straight) It should follow that 7/5 bonus poker (which is down 1 on the full house and unchanged below that) is a much better game than 8/5/4 double bonus (down 1 on full house, 2 on flush, and 1 on straight) 8/5/4 double bonus is barely a 94% payback game. Even 6/5 bonus is much better than that at 96.9%. I haven't looked at all the games on the HRH machines, but I suspect they have to offer some variants that are at least at 96% if you're playing 50 cent credits, and they probably have at least 1 that is 97%+. VPFree suggests they have 99.17% payback 8/5 bonus at the high limit bar for single line dollars.
