    Keiran,I spent some time over the last few days studying and getting
    familiar with Gregory's technique you sent.It took some digging and
    refamiliarisation with the haversine tables but I see how and why it was
    accomplished.All my questions were answered.
    Do you have another technique for finding variation you can share with us?
