Hi all, I have used the calcpos routine to calculate hundreds of thousands of map pin positions. I then use the results to recreate the pins later. The accuracy I have found to be within just a few metres so, even though you may be justified in your observation, in practice and using MP2004 this routine works exceptionally well.

Cheers

Chris
