Why Arrow Switch?

Members have asked why the Club uses an Arrow Switched movement to determine single winners of a pairs event.  The attached article, Determining a Single Winner Result for a Pairs Event explains that the arrow switched movement is considered the fairest means for determining single winners.  The result is not perfect but as near perfect as one can get when playing bridge.  Theoretical analyses behind the accuracy of the logic are complicated and not for the faint hearted.  If not convinced by the article, your next step is a “Google” search with my best wishes.
