i hope the speed play of your video is mixed or edited for appear fastest.
(cause i could be wrong , but at that speed....i could call it unhuman-snapping)
dont get me wrong, u are a nice person.
Thanks for your words bro, no, it is not edited, my mouse sensivity in marksman mode is a little fast, that's why it looks like snaps, you know? Try using1200DPI, 7.3 sensivity and 0.730 in marksmanship, your aim will fly!
