WebA ratio of 0.5 is logically symmetrical with a ratio of 2.0. In fact, in some cases the decision about which value to place in the numerator (with the other in the denominator) it is pretty arbitrary. So the same results could be expressed as 0.5 or as 2.0 depending on the whim of the investigator.
