I will delete all of the NG builds as all of that code has now been merged into 
master.

You gave the reason why there is a Subsurface setting yourself.
Most dive computers don't tell you at all what GF settings were used (and many 
don't use Bühlmann, anyway). And the Shearwater doesn't tell you if and when GF 
was switched. Subsurface calculates its own deco ceiling and visualizes that in 
addition to the dive computer reported ceiling. And the Subsurface GF settings 
control THAT calculated ceiling.

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

I am not sure that this is generally doable.

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.


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.


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.


Kind regards,
willem

There are two portions here. The deco calculations done by your
computer, and whats done after the fact in subsurface.

Both can be displayed in the profile.

The subsurface setting affects the deco calculations that subsurface are
doing, on the data (depth / time) from your dc.

If you're to change your deco settings while diving, that will just
affect the deco data generated by your computer.


This way, you can compare dive computers deco algorithms with the
subsurface implementation.

Maybe we should try to clarify the gf settings ontop of the profile so
its clear that those are the settings that _subsurface_ are using, and
not the ones from the dc.
