I ended up turning off one tank as it had not started drawing from it yet. And as it worked out, the "in use" tank ran out around midnite. I went out and flipped the regulator lever over, and turned the full tank on. I waited til the net morning to change the empty tank. But I did get a good idea of tank life expectancy. I will keep track of the next tank when it runs out. Then I will get a closer idea of how long they last. I can base refilling empties with that info.
After three pages with this thread, the solution is to try to get a handle as to how long it takes to run out and swap bottles before that happens? :S
