when it comes to penetration. Some casinos just can't stand for anyone to have a chance to win and just cutoff 2.5 decks out of 6 (Imperial Palace) so that they don't have to watch anything. Some casinos have shitty games and still sweat them like they're dealing to the bottom (the 6:5 games are a good example of this).
Other casinos don't think many people have the skills to get an edge and deal very deeply to maximize rounds between shuffles (and consequently rounds per hour) and then smartly watch their games for players who might have a chance to beat them. Other casinos try to strike a balance between the various penetration options.
When a casino deals 75% at double deck it is not by accident. The table games manager made a conscious decision that he would make more money dealing more rounds per hour by dealing deeply than by shuffling more often. When we post about pen at certain casinos we should just state the facts without extra embellishment. For example, when talking about penetration we should simply give the basic info...The Palms deals 50% on their 2D game, Suncoast deals 80% on their 2D game.
The info that is damaging to disclose on public websites is the other stuff that characterizes a casino...especially its game protection...especially positive information. If I were to say that Suncoast deals 80% at 2D and takes table min-max bet spreads without blinking from all players I would probably be responsible for getting a game burned out very very quickly (don't bother...they sweat the action like all of the other Coast properties). However, mentioning negative information is useful as it saves all of us time that we could be spending playing or searching for better games elsewhere..
