Hello guys I got a genuine question. Does anybody else struggle on long ranged duels with vandals/phantoms?

In general my aim is pretty good and more or less pretty consistent (I'm not making many mistakes in terms of crosshair placement or shooting). But when it is a long ranged battle I just suck. It's like no matter how good I adjust my crosshair I just don't manage to be on the head. I truly don't know why that is but I am just garbage at that. For example fighting on map pearl at B main/long: Player 1 at ramp and Player 2 at screens/site/hall. These types of duels I lose like 80% of the time.

Just for context/info:

• I'm immortal 1 atm
• I play on 800 dpi x 0.3 sens
• on resolution 1280 x 960 stretched

I've been wondering if it might be the res for me. But I really dislike the 103 fov on native res and aiming feels much harder for me on that res.

Maybe my micro adjustment is just really bad on smaller targets/heads.

I would be very interested on your opinions.
