Not an issue. I used as my test time the point the Esbit tabs expired - about 12 minutes, give or take a few seconds. That was when I did my sampling of the water temp. in all three vessels.

How many Esbit tabs to get the West German pot to a soft boil without a windscreen? In my experience, 2.5 to 3. And about 20+ minutes. WIth a windscreen: 1.5, and about 15 minutes.

I'll stick with the Cliff's Canteen Cup Rig, or the Trangia.
