<p class=MsoPlainText><font size=2 face="Courier New"><span lang=EN-NZ
style='font-size:10.0pt'>I had thought that there were discrepancies brought
about by a hypothetical bug in therion due to lengths or point continuations
flagged 'explored', 'approx', 'duplicate' or 'surface' not being allocated
correctly, but a partial and informal test that I did seems to discount this.<o:p></o:p></span></font></p>

<p class=MsoPlainText><font size=2 face="Courier New"><span lang=EN-NZ
style='font-size:10.0pt'>Usually the pdf map reports a shorter length than the
survey-list, but on doing some testing with a particular project that had this
behaviour I managed to find a subset selection of maps where the pdf map
reported a longer length than the survey list for that subset survey-list.<o:p></o:p></span></font></p>
