Is it generally true that: The lower the playing correlation of your system with a given playing decision, the less you'll lose by simplifying the index number for that hand (a la KO Preferred)?
And while we're at it, I wonder if anyone has come up with a formula relating the volatility of ev gain near a given index number to the PC, frequency, and avg. bet size of that hand. I would think those would be the three factors we'd want to look at to determine how much "fudging" we can get away with.
