     George Huxtable advocates this "simple message":
    >  "Plot a point, at the centre
    > of the triangle, but be aware that the true position could lie well
    > outside that triangle."
    Since this is a somewhat "tendentious" (lovely word, that) argument
    about statistics, isn't the chance of the "true position" lying within
    one standard deviation of a position line about 70% ? (Whilst
    retaining the assumption of a standard distribution of error.)
    And within two standard deviations about 90% ?
    What evidence can you present, George, for the "true position" being
    at all likely to lie "well outside" the triangle - or other shape?
    Is it not correct that the most likely place to find this "true
    position" is close to the position line?
