Other VPM-B implementations (V-Planner, MultiDeco, Fortran code) take the default gradient of onset of impermeability as 8.2 atm. We use bar as the pressure unit, and 8.2 atm = 8.30865 bar.
This has negligible effect on all of the calculated plans I've tested, resulting in a maximum decrease of 1 minute in total dive time for ~150 m deep dives, but we should get unit conversions correct anyway.
