Hi All, I'm examining the differences between Bühlmann and VPM-B and I noticed an oddity with the individual tissue graph on the planning profile and for actual dive profiles. The dive starts with supersaturated tissues.
Look at the attached screen captures. I expected to see the green and blue tissues to start below the grey line (ambient) but clearly they start supersaturated, the fast tissue is at maximum supersaturation. During the dive the tissues don't change. Also (not shown) you'll see that the ceiling changes as per gradient factor configuration. This isn't how the Bühlmann tissues chart. Should I be expecting this to chart like Bühlmann or is VPM-B that different that a chart isn't relevant? To reproduce use 4.5.4.11, open the Planner, select VPM-B -0 and turn on tissue graph. A default dive profile should show the problem. Also the Shearwater-like tissue graph in the information box reflects bad information too, 10 seconds into the dive it shows near maximum saturation.
