Suppose you hit your original ball 260 yards into the cabbage and then top a provisional ball 100 yards down the middle. You can continue with the provisional ball until you reach or go further (closer to the hole) than where the original ball is likely to be. If you find the original in bounds within 5 minutes, then it is still the ball in play and you must continue with it, even if unplayable, when the normal options apply. You are not forced to search for 5 minutes; you can now just walk up to the Provo ball and play that, accepting a stroke and distance penalty, with the original ball being lost.
