It's the actual amount on my water bill. And yeah. 2-3 toilet flushes a day. Probably a 3 minute shower. A gallon or two for plants. The biweekly high-efficiency washer. (And I'm sometimes traveling but much less so recently.) The weekly dishwash. Etc. Surprises me too. But that's what the numbers say. Not even trying to be unusually convervationist.
