    I will try to explain.
    A navigator using plotting techniques introduces greater errors
    which stem from these techniques (placing a ruler, drawing line along its
    edge are not exact operations, especially on a small cluttered badly lit
    table which rocks back and forth). Assuming your AP is within a degree,
    the error introduced by Hilaire method would be smaller then the errors
    introduced by the act of plotting lines. Doing second iteration would be
    a waste of time.

    Thanks for kind words, George. I've been reading the list for a past few
    years on and off and I make occasional post or two now and then.
    I've learned a lot from this list. And it is a place like no other.
