One thing that blackhole says is true: APs seem to leave the RNG out of their equations. They just don't account for a long string of an RNG not cooperating with their expert holds.
That's the problem with trying to be an expert at video poker: the darn RNG just doesn't give you that card you are drawing for.
Even our friend Arcimedes has had extremely long droughts when drawing on four to the royal. I had a royal flush drought that lasted more than a year.
