Far to Nightingale - The Rose Diagram

Several biographers have reported that remark as being written by Far to Nightingale. She was telling him to play it straight and avoid editorialising. How could she produce the famous Rose Diagram, an artfully constructed piece of statistical storytelling? My guess is that she was far too clever to build an argument on shaky foundations. The more spectacular the statistical acrobatics, the more solid the numbers needed to be. I don't even know if this cautionary tale has a happy ending. If the end justifies the means, I suppose it does because she won.
