Does that mean food, water, and fuel included? If so I really don't see how any number I could come up with would be all that meaningful since it will vary hour by hour and day by day by as much as several hundred percent. How do you manage that? Go with the likely maximum? The likely average? The likely minimum?

Generally I would have no idea what that might be at any point in the trip at least not in advance. I guess I figure out what what I start with, but that is almost always with no fuel and almost no food. I do include a few consumables in my count like soap and sunscreen, but they are usually only two ounces or so each.

Edit:
I see that you already answered.
