    | How have you calculated this, Frank?

    comment from George-
    
    I share Peter's doubt. While there's no doubt that using lunar
    altitutes will always give a reduced accuracy than lunar distances,
    and a factor of ten could indeed be possible under certain
    circumstances, I do not see how such a factor could be "typical". I
    hope Frank will explain further, or pehaps amend that claim. What
    "typical" value does he presume for a standard lunar-distance
    observation?
    
    George.
