Depends if you're concerned about the max weight you'll be carrying or the average over the whole trip.

Being a little more concerned about my pack at the heaviest,
I tend to start looking hard at using a canister stove at
more than about 7 person days of cooking. (Which does mean for
99% of my backpacking outside of winter I use alcohol)
