You may be right. Baseball aside, I know what it's like to fire off rounds from a handgun. I'd love to see a study that's measuring decision-making between shots, and not some other unrelated action. Firing that second shot isn't a new decision-making process. It's a continuation of the one you're in. Close to two seconds is not a short interval when popping off rounds. Now if you're saying that once the first shot is fired then it's decided the trigger is getting pulled until all movement ceases, fair enough. That's more a matter of philosophy than physiology.
