    Question CVCX risk

    The risk in CVCX doesn't seem to add up. It always seems to have incredibly high risk. I plugged in the Blackjack Apprenticeship strategy, which is just standard basic, Hi - Lo, and deviations. With 1000 units, it says theres a RoR of 7.4%. With 500 units it puts the RoR at 30%. Every time I see a screenshot of the software it seems like other people have the risk way lower somehow. I found a reddit thread of someone else having a similar problem, although I couldn't find anything good in the comments: https://www.reddit.com/r/blackjack/c..._between_bjas/
    If CVCX considered trust worthy? What about the BJA software? How many units would you want to play with? Does 30% RoR with 500 betting units sound accurate?

    As I understand it, the BJA software isn't a simulator. It's just a table lookup. It probably uses CVCX for the data.

    Your screen shot of the results is missing. In the results screen, click Export at the top, then the second export button. Create an export file and email to [email protected]. Then I can see all the settings and data files.

    Looks reasonable to me for 50% penetration. Show me a screenshot from someone that shows a lower risk.

    God damn, I wasn't even thinking of penetration. I didn't realize how huge an effect it has. I brought the penetration up to 75% and with 1000 units it hays ~1% RoR. Thanks for responding and helping Norm. Now all I have to do is find a double deck game with 75% pen in real life.
