Forum:Beat IW's best time on "The Pit"

I've become obsessed with trying to beat IW's best time on The Pit. I've been using the M9 and USP. I turned aim assist of cause it doesn't take my movement into account and keeps targeting over the targets left shoulder. On my best run I missed no shots and scored 22.80 seconds- could someone please advise on how to get 0.2 seconds faster.
