If I'm not mistaken, the $threshold is the minimum match lengh.  From
"perldoc String::Approx":

       The implicit default approximateness is 10%, rounded up.
       In other words: every tenth character in the pattern may
       be an error, an edit.  You can explicitly set the maximum
       approximateness by supplying a modifier like

               number
               %numer
