I like using CVdata Index Generation to see how different rules affect the indices.
Lately I was wondering if I can see the EV gained from using each individual index. It would be nice to know how much I'm giving up if I decide to simply not bother with some of them. I already decided I'm not bothering with below -1 (because I'd choose to leave the table, or I'd be betting min), and not above +8 (less frequent), but maybe EV would be a better way to make the decision.
