Negative deck

What is the probability when playing a SD H17 double 10,11 50-60% pen with three players at the table and never have a positive count after 40mins of play?

In single deck? Pretty small unless the players are super slow.

Was the dealer dealing a consistent number of rounds per deck? There might be a threat of preferential shuffling any time a count got positive.

No idea. I'd guess on the small side cosidering trues of +1 or more probably happen 25-30% of the time anyway.

Never a single +RC at any time, even on the first card?

Might be the time, to quit and watch. See if all the 5's and 6's show up in an hour or so.

Anybody think the pit will spread all the cards face up if asked by the player?

Would a player have a right to demand this in Vegas?

Umm, not having a positive count would mean the dealer was holding out LOW cards, which would make this a positive expectation. The dealer could have been holding out lows to let an associate bet. It's when you always see high counts that you should start to get suspicious.

Personally, I would have sat down and started flat betting a decent unit, and see where things went. You probably had an edge.

You're right moo, I guess there's two different ways the dealer could be influencing it. If they're somehow stacking the shuffle so that high cards come first, then you'll see counts that always tail off negative.

If they're merely counting along, and shuffling as soon as the count turns positive (before that hand is played), then you'd see variable rounds between shuffles, with some short decks (one hand), and some longer ones.

Or it could just be dumb luck. But preferential shuffling is pretty easy to notice is you're keeping a count. I mean, even *I* noticed it when it happened to me.

No preferential shuffling ,the dealer shuffled up after the same amount of rounds each time. There was never a postive RC after a round was dealt. I decided for the latter part of the session to bet half a unit. I lost a lot more hands than an average session, but just a little money because I had min or less bet out.
