Sticky question

8x HA would still give you a 47-48% chance in most cases...in some of the worst games out there it might be 45%. I still can't imagine the EV is better than that for some other betting system. Maybe it is, but I've never seen the actual math for it. Anyone have anything besides reassurances without proof (not trying to be a smartass at all, but that's what you guys gave me).
