EV adjusted for penetration

[Persnickety1]

There are many good EV calculators available online where I can research what the house edge is given a set of table rules.

Can anybody please point me to a web site, preferably freeware, with calculators or graphs that could help me adjust the EV of a game for a specific penetration?

Everybody knows that a game with EV=-0.448% (6D,H17,DAS, surrender) is not as great as a game with EV=-0.543% (6D,H17,DAS, no surrender) if the penetration on EV=-0.448% is lousy and the penetration on EV=-0.543% is great.

Is there a rule of thumb for determining just about how much additional penetration is required to negate the effect of a bad rule, like maybe the lack of a surrender option?

I found some promissing charts on the QFIT site, but apparently those are password protected, only for CVCX users.

off the top of my head i think your numbers are wrong....

6D H17 DAS, LS ~0.54
6D H17 DAS ~0.62

Blackjack Attack has a crapload of tables which explore those very same questions. Most of the tables were developed with (drumroll), CVCX.

Not CVCX, with Karel Janecek's SBA - Statistical BJ Analyzer. zg

I think the later editions (or Chapter 10, anyway) switched to CVCX.

Errata -

"Not CVCX, with Karel Janecek's SBA - Statistical BJ Analyzer." In Blackjack Attack third edition; the SBA tables were replaced by tables generated with CVCX. -norm

I would like to hear if there were any appreciable differences in the new tables. zg

Well, they were ready 100 times sooner! :grin:

"...CVCX creates this data at about 100 times the speed of SBA and 1,000 times the speed of BJ678"

Try this:

And is exactly why the the units are equal to 1/2 the change in e.v.1 unit for every .02 change in advantage. Also 1/2 of 42 =21 and 2/3 of 63 =42 this is why it ends the way that it ENDS.

6 div.105=1n17.5
total:105 divided by 6= 17.5 please note: all are increments of 4and6 and expand 1-21 1/2 of 4and 6= +2 and +3 exactly where we started from. which is exactly why the second number in the t.c and r.c is 50% more. And is exactly why the the units are equal to 1/2 the change in e.v.1 unit for every .02 change in advantage. Also 1/2 of 42 =21 and 2/3 of 63 =42 this is why it ends the way that it ends. As a matter of fact all im really doing is adding +2 and +3 for every 1/4 deck. Of course all this changes with your advantage. but the patterns are the same.

Im still fairly new at computers and typing, so if this is sloppy please forgive me, im getting better. Im attempting to correct the sloppiness.
