Interesting article and thanks for posting.
It kind of seems, like many other things, that shooting on the move is worthwhile to have in your bag of tricks.
I remember a stage, at a USPSA match quite a few years ago, that was similar -- three targets that had to be passed and engaged. One passed close enough to them, and they were far enough apart, that I was able to double tap each shooting one handed as I moved by them at a fairly quick pace.
