Fuel efficiency is the holy grail of most backpacking cook kit developers.
IME the key to efficiency is matching the components, so they work together in a harmonious manner.
Your evernew burner puts out a lot of btus' so would suit a larger/wider pot or maybe one with a heat exchanger (heat exchanger pots don't usually work with lower output meths burners, too much flame quench) to take advantage of the extra output.
The kit as it's sold is a complete mismatch of parts IMHO.
People don't often appreciate the importance of a windshield, not since a windshield was a piece of canvas held down by two bike spokes, has a windshield just protected the burner from wind.
A proper windshield (in a backpacking situation) shields both the burner and the pan completely from wind, creates a chimney effect and often contributes to holding it all together.
A rough guide to how efficient your set up is, is to check the temperature of the fumes/air coming out of the top of your windscreen, really hot and your pan hasn't absorbed all of the heat out of the flame and your set up is heating the air around you wastefully.
This isn't an absolute measure, as said before flame quench is just as inefficient.
My testing shows a pan twice as wide as it is tall is the most efficient and stable.
So you can spend 10 years developing your kit, measuring fuel usage, exhaust temperatures, stability, temperature differentials etc or you could buy one.
