Downloaded subsurface recently and playing around with its planning tools and beginning to really like the program and plan to implement it into my dive planning.
When planning some BO deco for CCR diving using the "Bailout: Deco on OC" function, I get the following warnings sometimes: "Warning: not enough reserve for gas sharing on ascent!"
This pops up when it is saying I will need 24cuft of O2 for deco when I am carrying a 40cuft 02 bottle in the plan. If I bump up the fill pressure in the bottle a bit or switch to a bigger bottle, such as an al80, this warning goes away. For this specific plan, the warning goes away once my plan has 46cuft of O2 (1.92x). My question is what is the default setting for reserve/contingency planning and is there any way to change it? I didn't see anything in preferences or dive parameters. General recommendations are to bring 1.5-2x the deco gas you need. 1.92 is almost 2, but not quite. Is Subsurface doing some other calculation to determine how much deco gas I should be bringing rather than a simple 1.5 or 2x factor? Interested in their planning logic behind the warnings.
