Gas consumption and SAC calculations:
_Subsurface_ calculates SAC and Gas consumption taking in account gas
incompressibility, particularly at tank pressures above 200 bar, making them more accurate.

- Define the amount of gas that the cylinder must have at the end of the bottom section of the

need to bring one's buddy to the surface using gas sharing. How much gas is used in
sharing depends on the depth of the ascent. This can be a bit hard to estimate, so most agencies assume a
fixed amount of gas, or actually of pressure e.g. 40 or 50 bar or 25% or 33% (rule of thirds). But _Subsurface_ can do better
because it knows about the ascent and that is why we add the amount of gas during the ascent (i.e. the "deco gas“).
