* Did I mention how bat-shit crazy divinglog is? The sample

*
* Crazy stuff like this is why subsurface has everything in
* these inconvenient typed structures, and you have to say
* "pressure->mbar" to get the actual value. Exactly so that
* you can never have unit confusion.
*
* It gets worse: sometimes apparently the pressures are in
* bar, sometimes in psi. Dirk suspects that this may be a
* DivingLog Uemis importer bug, and that they are always
* supposed to be in bar, but that the importer got the
* sample importing wrong.
*
* Sadly, there's no way to really tell. So I think we just
* have to have some arbitrary cut-off point where we assume
* that smaller values mean bar.. Not good.
