Meaning of cavelength

I might understand something wrong, but it seems to me, that what is called `cavelength` in Therion is actually the length of all centerlines. This might correspondent to the cave length in straight caves but certainly not in labyrinth like caves. I was told about the "Kluterthöhle" in germany which was surveyed in the 60ies to ca. 5900 m and then resurveyed and recalculated - to have only a length of 5200 m or so. This is for on the one hand a problem with circular shots inside big rooms, like http://filez.foxel.org/3s3H0d2X361A0K222Z3N An other problem are crossroads like http://filez.foxel.org/1t0C0r2Q011i0g1L0i00 where you can't young the shared area of two passages twice but must - at least to what I have been thought - deduct some part of the centerlines: in the following picture I have marked the parts being considered cavelength yellow and the centerlines not counting as part of the cavelength red https://img.skitch.com/20120221-jhraj625isy8j1i9naxiki3b76.png Certainly I'm not the first person stumbling about this. What is the preferred way to approach the calculation of cave lengths? Regards Maximillian

This works. team "Nic Barth" station team "Bruce Mutton" dog instrument station "Nics Garmin Etrex GPS" If 'station' is replaced with 'instruments', it also works fine. However this crashes on the first line. team "Nic Barth" position team "Bruce Mutton" dog instrument position "Nics Garmin Etrex GPS" with the error D:\Program Files\Therion\therion.exe: error -- ArthurNorthAreaINDEX.th [674] -- unknown team role - position Therion Book p18 suggests it should work OK
