[Therion] Incorrect depth generated for legend

>I'm assuming that therion uses the vertical difference between the highest
station and the lowest station to generate the depth number without regard
to LRUD data, is this correct? 



>And does anybody have a suggestion for how I can easily get the correct
depth output onto my map? 

You can add some tex code to a layout.   See


  code tex-map
      \cavedepth{300\thinspace{}ft}  %forcing reported depth to 300 ft



>I can see how this could be a significant issue if you had a cave with
little vertical extent except for a high dome. You would have to shoot a
shot to a station at the top of the dome to capture it's vertical extent in
the legend data.

That would avoid the need to manually edit the depth each time you suspected
a new survey might change the depth of the cave.  It would be my preferred
method, even if it means creating an artificial shot to replicate the 'up'
data.  It would need 'flags duplicate' to prevent it being added to the
reported survey network length.
