    That would agree with my suggestion if and only if the cocked hat was
    equilateral. Otherwise the contours of equal probabilities are
    eccentric so as you can imagine (under these assumptions of Gaussian
    errors) you are more likely to be in one direction than another
    putting the point of maximum probability off the line joining the two.
    
    But as you say, the line between them is the quickest you can do
    graphically by hand, and you just would trust it less with a very high
    aspect ratio cocked hat.
