when you say micro regulator + optional windscreen, isn’t that essentially the same as the windmaster?
Uh, no. Two very different stoves. The MicroRegulator’s burner is convex whereas the WindMaster’s burner is concave. Not only is the WindMaster’s burner concave, it’s recessed down inside a lip, a lip similar to the MSR WindBurner (formerly known as the MSR WindBoiler). Further, the pot clearance is slightly less overall. The combination of these three changes make for a more windproof stove.
In every test I did, and I did a lot of tests, the WindMaster always boiled water faster, even in still air. The WindMaster really pulled ahead in anything more than a light breeze. I did not do “gale force” testing with the WindMaster, no upright canister stove can stand up to that (well, except for specialized integrated canister stoves like the WindBurner or the Reactor).
Fuel consumption per minute appears to be about the same between the two, but since the WindMaster always boils faster, it uses less fuel. Average difference for a two cup boil is slightly less than a gram, but if you round off to an even gram saved per boil, you can use that for some rough calculations.
Let’s say you have a MicroRegulator, you do two boils per day, and you use 10g per boil. A 110g canister would last you 6.5 days with zilch left over. You might use that last 1/2 day’s worth of gas as your safety margin.
Now, let’s say, you cut your use by 1 g per boil. A 110g canister would last you 7 days and a little bit of change.
So, you’re basically getting about half a day’s worth of “savings” by using the WindMaster. There are trips where I know I’m cutting it fine on the gas and it would be nice to have that extra half a day’s worth of gas. YMMV.
