And yes of course you're right. The expected loss can in almost no cases be the effective result after earning as little as 1000 points needed play in order to get a  free buffet.  I also play deuces wild and learned that the short term swings are mostly influenced by how many wild royals and 5-of-a-kinds I see during one session. Technically you can be even after thousands of hands even by not hitting the 4 deuces. But that only works if you get too many wild royals and 5-of-a-kinds. Otherwise you lose for sure.  If the stretch of not hitting the deuces goes through 3 or more days then it's a bit annoying. My results, including my high error rate in a long sessions show that I can barely break even even with 1 set of deuces if I play sessions that are longer than 12 hours in one day (with break times of course). One Royal per week is needed to cover these gaps. But we all know how hard it is to get them.
