Yeah, but IIRC each corner it goes around takes half a step off of it's effective radius; it has to go into the square past the corner and then to the space around it instead of moving diagonally through the space where the wall is. It no longer has a fixed volume unless a fixed volume is specified (unless they changed it back after 3.5)
