Query: Great little coffee maker

This little percolator makes great coffee, and very hot. It's difficult to find small coffee makers that are not of the drip style. The only reason I gave it 4 stars rather than 5,is that it is difficult to determine the max water fill line. There is a 4 cup line, and then another line just above that. Is that line the max fill line, just in case one wants to squeeze out a little more than 4 cups?
