It's borderline at max +3. But, set the max at +4, which is the actual optimal max bet if you want an index. In the end, it isn't going to matter to how much you make in a year. Going back to CVCX after generating all the RA indices that you are going to use will likely increase the bets. And may increase the max bet to +4 with Rational Bets.

If you use RA indices, you're going to double fewer times.
