sens doesn't matter, raw input matters a lot but if you're used to the acceleration it may not be worth it to switch over. my opinion would be to set your sensitivity to something that's alright for you, then lower it until you're comfortable
About 4 inches to go from the left edge to right edge of my screen for me. The muscles in my shoulder have the most muscle memory for me, and that's the sensitivity for me that seems to exploit them the most.
Raw imput 800 dpi with sens depending on star rate map ... it may differ + 8 dpi or - 8 i mean... for 3.0 star map 300 dpi for 3.48 348 dpi for 351 still 348 dpi xD for 4.0 400 dpi for 5.0 500 dpi etc... that's my cutie style i change my sens for every map also during multi player .
