“As for altitude as a variable, the boiling point may be a tad lower, but the amount of oxygen for the stove is lowered as well. There is probably a net loss as you gain altitude - just surmising.”

I’ve always noticed I get better boil times in them there UT, CO, WY mountains than I do in the Midwest. So I would incline to think air pressure is more dominant a factor than oxygen, on the crust of this Mother Earth, for alcy stoves.
