I believe it was Oscar Wilde who said, "Nothing succeeds like excess."

(Oscar was generally considered to be an elegant.)

15,000 shots in four days is 3,750 shots a day. If we allow 4 hours to eat, sleep, relieve oneself, and brag, that leaves 1200 minutes to shoot those rounds (or 3.125 shots per minute for 20 hours each day for four days, better than a shot every 20 seconds). And . . . he also shot three elegants in his pajamas.
