Most people use custom advanced controls on apex legends and it feels a lot better than the recommended settings to use on this site, would it benefit people if the ST was retrained around the best advanced settings where you can very precisely adjust yaw and pitch values for hip and ads individually?
Lucifalic is right...There really is nothing that can be done on the retrain. It’s game speed and movement that makes the ST feel incomplete/inconsistent.
What I recommend set your xim and mouse to your preferred response rate/dpi I personally think 500hz is the most practical and balanced dpi is personal.
Go into the range move the mouse around with 7/7 settings...then switch advanced on. Most important thing to set is DZ that gives smooth takeoffs with the crosshairs while making sure your response curve is somewhat near desired setting.
Response curve is personal but usually the final setting will be either 2 clicks above or below default. Find your feel mate!
