It looks as if 3 is the correct number for an area. Incidentally you can define a VOLUME with 4, which is needed for the filler. I'm guessing that the redundant landmarks don't pop out, so if you use one in each corner one won't pop out. Also I expect that if you place the machine next to the redundant one it is ignored.
