Yes, The WC literally/figuratively boxed themselves in. If they would have plotted Z222 on the west end of those lane markers, everything would be hunky-dory, but Their time and place sync (Z222/snipers nest) for a back shot just doesn't work. Unless, the box was transparent, used as a silencer and bullet speed reducer(triple purpose-quite clever) shooting through it, then it all makes sense. Especially that shallow back entry. Anyhow, the math for Z222 is: 490
