Current CW does it differently from most others because of the yin-yang arrangement, thus its higher density. But the difference is one of degree, not of distinction; only a completely unthinking person would say that moving from current CW's "2-4-2" to the new "1-2-1" means double the space or half the density (although I acknowledge that there have sometimes been such people posting on FT). Take any similar cabin and draw any horizontal line across the aircraft: it will almost always cross some part of each of 8 seats.
