title: Count of consecutive repeated value only when repeated 3+ times
body: <p>My goal is to count and potentially conditionally format the occurrences when a certain number of days pass with 0 sales.
  I am trying to return the number of times 0 is repeated consecutively 3 or more times. So for this example I would like to see the return value of 3.  So far I can't wrap my brain around how to do this, any ideas?</p>
