Norm, with single deck CVData, I notice you can not set fixed rounds under setup when computing indices and the instructions say to be sure to check the fixed cut card box. If you do check fixed rounds, you get a message when you start the sim that says: "The starting card is too high". This is located in the options block on the indexes tab. The lowest you can set it is 1.

In any event, I think the indices would probably be the same. Is this so?
