How much gas is used in + 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“). |
