Yeah, not sure where the 1 second tops is coming from. Volleys were visible for some time. It was an effective psychological tactic as well as militarily powerful.
So no, Elim, with his head on a swivel he'd have had time to see a shot was made. And why he wouldn't "just barely" dodge as opposed to change direction entirely is evident both in terms of efficacy/statistics as well as standard instinctive psychology. You don't make it a bare miss. You make sure.
