That does not really cover this case, or would be tedious to type in. Every
time you change direction with an instrument (using a forward instrument
backward or backwards instrument forward) the *calibration would need to be
changed. So yes technically it can be implemented in Survex, but not
really. I would suggest this format is needed to allow users to put data in
as the collect it without a hack/bodge.

I did not ask you on expo, only came across it at Eurospeleo
