The pace of an evil mastermind’s wicked scheme is determined by the plot and only the plot. This is to give the protagonist, whether it be a suave spy, dynamic super hero, or plucky band of adventurers, time to much around and do others things and still arrive just in time to thwart the villain (or watch the world burn). So no matter how many burning buildings full of small children or seducible henchwomen are between the hero and their goal they will always arrive just in time for the villain to be just about ready to enact their dastardly plan. Much to the chagrin of the bad guys.
