I may have misunderstood but I always thought the Harris Matrix showed the order in which things happened (chronological). meaning that there would be no problem in representing deposits of soot etc on ceilings. The problem would be if someone tried to infer physical relationships from the matrix. The problem comes in trying to imagine the 2D diagram as a representation of a three D space. Up, down, next to, above and below have no meaning in the matrix where as before and after do. Or do I have to go back to the book?
