            I figured that out , but would pose more sense if there
            would be no subsurface setting in this matter. It makes no
            sense to setup the dive log to display 30/75 when the dive
            computer reports it was using 30/70 for that dive. Even more
            what if during a dive I change the GF settings on the
            computer (which is possible on th eshearwater)??? what will
            subsurface than display? it should display a icon in the

                </span> I suspect here the GF on the left (30/70) is the
                gradient factor that the dive computer used. This is a
                function of the dive computer settings. The value on the
                right (30/75) is  the GF that Subsurface has been set to
                in the Subsurface Preferences (i.e. the displayed
                profile GF).<br>

      I am not sure that this is generally doable.<br>
      <br>
      Firstly, only a handful dc's record GF. Most do not. How should
      one deal with the dc's that do not record GF? How should one
      provide for the multiple ways in which different dive computers
      determine conservatism? Most dc's use conservatism levels, not GF.<br>
      <br>
      Secondly, how is GF recorded in the Subsurface dive log? This is a
      function of the way libdivecomputer extracts data from the dive
      computer. I am not convinced that libdivecomputer has the ability
      to capture on-the-fly changes in GF during a dive, so your
      suggestion is probably not possible anyway. My Uwatec
      automatically adjusts the conservatism if the diver oversteps the
      deco requirements, but this is not captured by libdivecomputer.
      And I do not care too much about that.  If this is a critical
      factor for you, then consider a dc like Shearwater that provides
      its own set of dive ceilings for each dive, reflecting the GF
      settings of the dc, including on-the-fly changes in GF.
      Libdivecomputer captures that perfectly.<br>
      <br>
      Thirdly, the displayed GF in the Subsurface dive profile is a
      broad and general yard stick to evaluate the deco during the dive.
      Is it really crucial to modify the ceiling in a detailed way to
      reflect GF changes during the dive? All the a diver wants to do is
      to get a reasonable *overall* impression of how well the deco went
      in terms of tissue compartment gas pressures.<br>
