SD, ES so on and so forth. I also heard the other guy said "it should give you a point where it should it at long ranges".
Both sounds crazy, ES, SD and all the rest dont or wornt make your bullet shoot more accurately. And "It Should" lol. Like I said dont rely on gimmicks and crap just to sell. Do what you have to do and get out and see whats happening or the consistency of a round at 100 or long ranges. Take No short cuts....
