    Thanks for the insight Don. Would it not be the case that switching to RA indexes would increase SCORE and changing the bet sizing would allow us to keep RoR the same while increasing EV? Either way, I'm using optimal betting generated by CVCX so would that still be an issue?

    Reread BJA3, pp. 375-377. You can't increase SCORE by simply switching the indices. It's assumed that, when you do, the betting ramp will change accordingly. If, instead, you keep the same bets, then it's the risk that will be lowered.

    To restate what Don has said except in a different way.
    Theoretically, RA indices allow you to increase your max bet for the count in question. Practicality leaves you with the same max bet with that amount which theoretically would have been applied as an additional wager is now applied to reduce variance.

    Expected value goes down when you use risk-averse indices.

    However, it is worth it because with risk-averse indices your variance is reduced.

    In theory this should allow you to bet more aggressively for the same risk of ruin - meaning you make more money overall. If you don't or can't adjust your bet size, perhaps because it is impractical to do so in a real game, you will have lower EV and lower variance.
