exact resolution of indexes to perfection
will not affect your win rate. You can use just about any level one set of indexes for any level one count and get roughly the same win rate considering the human lifetime of hours plyed. It would only matter if you played millions of hours like in a computer simulation.
Instead of worring about indexes you'd be better off spending your time worrying about how you can get more money down in max bet opportunities or spend more time shopping for better penetration.
