    For equally spaced LOP's, bias errors cancel   (The cocked hat gets
    bigger, the uncertainty remains the same.)  Adding LOP's reduces the
    random error slowly:
    number of LOP's  ,        avg dist from true to MPP,
    Std dev of dist
    3,   0.51,   0.27
    4,   0.44,   0.23
    5,   0.40,   0.21
    6,   0.36,   0.19
    7,   0.34,   0.17
    8,   0.31,   0.16
