DD vs 6D

I forget with whom I was discussing this, but we were debating the frequency of occurence of high counts. My position was that the more decks there are in the shoe, the more even the count runs and the less frequently extreme counts occur. His position was pretty much the opposite.

It occured to me I could go to www.qfit.com and get the stats to back up my argument; so here are just a few to illustrate my point:

TC = +2: DD: 9.38% 6D: 7.57%
TC = +3: DD: 3.70% 6D: 3.51%
TC = +4: DD: 3.34% 6D: 2.65%

The above are according to Qfit's preset criteria, which in this case are 75% pen on the DD, and 83% pen on the 6D. Note the higher frequency of more extreme counts in DD DESPITE the lower pen!

Do not think in terms of percentage, but rather in terms of cards. 26 cards cut out of play is MUCH better than 52, the only way to do a real comparison is setting the DD pen to 50% or the 6D to 92%.

it is so easy to find a 92% 6D game?

Wouldn't 50% DD and 83% 6D give you one deck cut off?

50% DD/ 83% 6D = One deck cutoff
75% DD/ 92% 6D = 1/2 deck cutoff

1/2 deck cutoff > One deck cutoff, therefore:
75% DD > 83% 6D

This is in contrast to what OP stated, which was my entire point.

Sorry, I read the "or" in your first message, and thought it was "and". I'm going to bed now, before I make any other foolish mistakes.

...but this is more or less irrelevant, since DD games w/75% pen are rare at best.

The REASON it should be percentage, not absolute number of cards, IMHO, relates to the likelihood of more or less than average of the cards in certain ranges being locked behind the cut card.

But, to get back to the originial and actual subject, the distribution statistics I cited from QFIT for various TCs DO illustrate that the count tends to run more "even" the more decks in the shoe, and the less likely the player is to encounter extreme counts.

You can add single deck to the observation as well. In the shoe
games, the shear volume of cards reduces the effect of card removal.
If you remove two 5's from a 6 deck shoe there is little effect, but
the effect in single or DD is much greater. Other differences that
result for this condition are B/S and variations are less dependable
and BJ's will occur just a fraction less, etc. Also, shoe games are more consistent and chage their flavor gradually.
