    Greg,

       This gets better and better!

        Two suggestions:  Firstly,   add a footnote, that if only versine tables are available, the figure 1, near the centre of the proformae should be 2.  Secondly, print off on ruled paper, then the whole page can be used for a Mercator for your latitude, avoiding flitting to and fro.

    PS. In my post of 23 Sep I should have put Prime Vertical, not prime meridian, as you will have known.  I was afloat with F9s around!
