Much has been written about fuel consumption: here and here. (@BPL, membership required) These two articles are a few of my personal favorites there, and are worth the price of membership alone. I too have agonized over the concept, especially with canister and white gas stoves.
In substance, the articles attempt to answer a seemingly simple question: For any cooking system, how much fuel do I need initially (or per re-supply) if I need to boil X units of water per day? Add this fuel to the weight of the cooking system, and you have initial carry weight. The articles are focused on the lightest models in each stove category (Esbit, Alcohol, top-mount canister, remote canister, integrated canister i.e. JetBoil and white gas), but the concept is easily extrapolated to any stove. The study measures the initial carry weight as a function of fuel consumption plus the stove, windscreen, empty fuel bottle and heat reflector, if any. Initial carry weight does not include the weight of any pot, because they are may be vary with the trip.
With the BushBuddy and other woodstoves, these articles are useful for comparison only. The BushBuddy's initial carry weight is varied only by the minimal weight of the firestarting tabs you use. A wood stove's initial carry weight without fuel is less than all the stoves in BPL's study except the alcohol and Esbit stoves. When the fuel weight of the stoves are added, the initial carry weight increases above and beyond the Bushbuddy's initial carry weight (5.1, stove + 1.13, sparker + .25, tabs + 1, sack, estimated = 7.48) once you are boiling more than 10 pints for an alcohol stove or ~12 pints for Esbit tabs. (See Table 8). These numbers become easier to meet as the distance between resupplies increases, the number of hikers increases or the amount of pints required per day increases, naturally. For initial carry weights for boiling less than 10 or 12 pints, we are dealing with but a few ounces. This is probably negligible in all but the most stringent gear requirements.
And you get bonus points for style.
