Those spread sheets are interesting but nothing more than suggestive for practical use.

Fuel consumption by Trangia Mini-28 kit is quite variable depending on wind conditions & can't be calculated in advance with any real precision, especially on a beach or in open country, etc.

Also one can be quite wasteful. Although stove is designed to contain & carry fuel, I tend toward distrust and mostly just burn off excess.

Similar stoves are probably similar in this regard, though I've no experience.

In recent years I've gone back to Trangia as primary stove, for very light cooking; not least due to availability and cost issues regarding canisters.

When practical I frequently use a camp fire for more involved (though still crude & primitive) projects.
