Would you care to be a bit more precise in your data presentation, since others seem to have difficulty in matching your results? What weather conditions, altitude, wind, temp, size of pan, type, covered? with what? And at 0 degrees -sitting on what kind of insulation, windscreen? etc.

I don't doubt that you get the results that you think you do, but you either take data differently than many, or you have a "flair" for these stoves that you need to share if you wish to make any universal claims about the general performance of the stove.

ALL: This isn't an alky thread nor a hammock thread. We can and have argued about alky stoves (and hammocks) many times elsewhere. Try to come up some other on topic suggestions.
