I'm just curious what the ST data says regarding ADS. I'm assuming mist tested it during the training process.
They are the same (at least were a year ago). The choice and difference for users comes down to: in-game limited relative zoom sensitivity, or xim ADS profile limited.
I am in the ADS profile limited camp, because: ST was trained at max sensitivity so I expect it to work the best it can work when zoom sensitivity is equal to the hip sensitivity (relative zoom sensitivity 100 in-game). Use xim ADS profile to fine tune your final sensitivity.
Edit: actually there is also some extra information regarding my final statement "Use xim ADS profile to fine tune your final sensitivity." There's a line of thinking that there is a universal best value for final ADS sensitivity for all players, and that it is between 41% and 54% of your hip sensitivity at 93FOV that console game has hard-coded. PC guys have a whole science about this, matching small flicks or large flicks (aka. "screen distance") across different fields of view. But bottom line is that this is only accurate if the input is linear and without smoothing, which it supposedly is with Exponential Ramp ST.
