Take Scissors Away said that the article has so many holes in it that it would make great swiss cheese. I was asking him to elaborate on that, not on the different variables on collecting, analyzing and interpreting the data. He hasn't replied to that as of yet.
If a supervisor is discarding data, then that is destroying an official government document. The methodology should be uniform, e.g., x number of surveys at x time each day instead of doing it randomly. But then again, consistency has never been a TSA strong point.
