I’ve attached a gripped copy.

As you can see there’s a lot of fields. Thankfully they are all named sensibly.

Biggest ones are:
   - fractionO2 and fractionHe.
       These define the breathing gas on OC, and the diluent on CC.
   - averagePPO2
       The measured ppO2 in the breathing loop of the CCR
   - currentCircuitSetting
       0 = Closed Circuit
       1 = Open Circuit

Together they give enough information to know what the diver was breathing at any time.

Again, I’ve attached a gripped copy.

The CSV import has no options for Gasses, Setpoints, OC/CC mode, ppO2 Sensors, all of which are in this file. I agree the dialog is a limiting factor here. I think there is also a problem with how these concepts map into the Subsurface XML.

Fields are named similarly to the XML.

I’m wondering the same. I’ve attached a copy of that too (Bailout dive.xml) exported from subsurface. All three attachments are the same dive.
