Yikes, why do all of that when */5 will do the trick?

man 5 crontab. scroll down,

       Step values can be used in conjunction with ranges.  Following
a range with ``/<number>'' specifies skips of the number's
       value through the range.  For example, ``0-23/2'' can be used
in the hours field to specify command execution every other
       hour  (the  alternative  in  the  V7  standard is
``0,2,4,6,8,10,12,14,16,18,20,22'').  Steps are also permitted after
an
       asterisk, so if you want to say ``every two hours'', just use ``*/2''.
