-<p>These are raw tape lengths which include pitches, splays and surface-surveys. There is also some doubt that the parsing is 
-correct so maybe some long lengths are misinterpeted: compass readings as tape-lengths for example: LoadSurvexDataCmd
-in parsers/survex.py would be a good place to start.
+<p>These are uncorrected tape lengths which include pitches and duplicates but exclude splays or surface-surveys.

 This is work in progress (July 2020).
