Got back from a week in Vegas, Stayed at GVR. Wife who doesn't know about correct holds in VP hit 2 $4K royals on the same Dueces machine two days apart, She maybe put $500 total thru the machine. Her first royal, both in spades and both needing only the 10 occured within 5 hands of play upon arrival. Next morning within 50 hands. Cards were not in any particular order though. I on the other hand lost about $7k playing mostly Singer play.
My wife for instance will hold say a 4S and toss 3 to straight. She really has no strategy. Just goes to show how I believe the programs are. Myself playing as well as I can, by the strategy, lost.
During the hot cycles I noticed, not only because my brain can't recall winning streaks like some APers profess, when I increased denoms I would get nothing- like I was being punished. My last session while winning at $2 (hitting flushs,FH etc) and increasing to $5 Bonus poker, I went 16 straight hands without so much a pair. I believe that is impossible. I am sure any one playing also notices these repetitive recurring low pairs over and over, many times in the same positions. These are a few of the examples.
BTW - I hit exactly 2 royals in my life, the second happened at GVR while I was messing around playing a 10 cent machine. I guess I should play at nickles for 40,000 or so more hands. I really believe the technology allows some/most of the newer vp machines to recognize your play against it (the house) and deal accordingly. Could this be to thwart the 'advantage players' ?
This is my analysis after years of play and paying attention. YMMV
