Hi,
Gear Skeptic has just released his first video on "Backpacking Stove Efficiency".
This is "Part 1 Pot Diameter- Burner Size- Flame Level"

Worth a watch... very interesting..
Lids .. for smaller pots .. lids should be <6grams to be worthwhile in terms of weight saved.
Of course low flame level gives best efficiency. But pot size gets more difficult.

I want to see what he comes up with for wind effects...
