In my fiddling the burner configuration makes a lot of difference. A skinny vertical flame like the Pocket Rocket seems less affected than a broad flame like, say, a Simmerlite, where I've found a wide pot to be a plus.

Time to boil isn't as reliable a metric as grams of fuel used per volume boiled and, of course, the other variables need to be minimized (especially wind).

Still, for a specific person's kit this sort of experiment is a great one to conduct.

Cheers,
