I'm guessing you're screenshot is from Poseidon_MkVI_6-14_import.xml,
and if i look into that file, i see that at 7:00 it says in the xml:
sensor1="1.17 bar" sensor2="1.15 bar", and when subsurface have loaded
that file it says that you're breathing a ppO2 of 0.51 bar at 7:00.
Thats probably why the deco is way off.

All the deco/ceiling calculations are done in
calculate_deco_information(), and thats using entry->pressures.o2 to
compute the deco info based in ppO2.
