Hi Ezra, I got out my Murphy's Law book, and found the relevant part in Chapter IV, Section 3, Sub-section 21, Paragraph 12, lines 9-14

During our northwet winters I have to charge a couple times a week. The fact that engine speed and attendant fuel consumption relate directly to SOC saves me huge amounts of fuel. I don't even mind doing the finish charge part of the cycle as by then my gennie is idling. And it's always easy to get a jug of gas, even when the propane barge is broken down (see Murphy's Law for why this only happens when I need propane). Best regards Ezra Auerbach p.s. Thanks to everyone for the kind words and good wishes on my new job at NABCEP.
