Today is an "iffy" day. I find it hard to concentrate on standing still when I encounter someone. Of course, DM has a bit of a wildcard style of spawning, but I should still be ready to encounter someone before I actually do.
When I make contact with someone, I sort of panic where the whole "head level shooting" goes out of the window and I am often strafing while shooting. This is evident in my shooting error chart showing blue.
Maybe I should work on the MASS approach for now (Move, Aim, Stand Still, Shoot) to get used to seeing someone-and not firing off immediately.
