Very cool. I've been in the Air Force for 10 years. I've got the cush assignment right now - working on a PhD in Computer Science to go back and teach at the Air Force Academy again. I'll have to do a real job between here and teaching, and I really hope to get over to Germany for an assignment. Where in TX are you headed? SA?
Just recently started crushing my own and getting good efficiencies. Now, I did take into account the water absorbed that's why I said I collect about 3.5+ gals when draining after using 4.5+ strike water. I calculate the rest I need to get 6+ and its usually way less then my initial strike water amount.
I misread - sorry. I thought you calculated your boil-off by 4.5-3.5=1 gal. I see now that I need another cup or three of coffee.
