and obviously with any stove, you want to do a bunch of boil slash burn time tests to get an idea of how much luiquid fuel to take with you for X days of doing this or doing that.
Guesstimate by trial and error, you don't want to carry a stupid amount of fuel with you and only use half, or run out before trip is over if you need to heat up stuff more or whatever if the weather is cold or whatever.
I wouldnt overthing the stove thing too much, if the whisperlite works, use it.
certainly lots of other options out there though.
