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
dive profile just like a cylinder change. Right?</span><br>

<div dir="ltr">I have this dive opened on the
windows version of libdcNG continuous
build 4.7.8-81-gb930c39eade0. I see the dive
computer setup as GF30/70 but in the dive
profile screen it shows GF30/75. Issue of
display glitch? Please see attached
screenshot.

</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>
