As a longtime supporter of knowing your own specs, physically speaking, we support this. All of it. Everyone in America should know their forty times, their mile times, and where they fall on the grand bell curve of American speed.
If distribution works like it should, the chances are that you, reading this right now, sit somewhere firmly in the middle. Or, if you are like us, you sit a full standard deviation towards slow at 6.09 seconds in the forty, and possess Powerful Natural Slows.
Side argument: Powerful Natural Slows may be just as much of an evolutionary advantage as Actual Blazing Speed.
