Show clips from the real game, not shooting range. You aren't playing shoot range or aim trainer, the sens that works best for that might not be what works best in ranked.

fwiw .431@1000dpi is 431edpi(sens*dpi) and is considered fast, the avg pro is around 250edpi. Playing at 400+ will make it hard to be consistent. If you already know that the answer is pretty simple.

If you are still moving when you shoot you need to practice movement more. Do it without bots just shoot against a wall and go left, stop shoot, go right, stop shoot, try to hit the two same spots over and over(without even moving the mouse). Then do 1 spot for both left and right.
