Dave, I appreciate that cynicism is your default option, but in this case there is a fairly simple cure for your fascination. As
skyluxe said, you will indeed find the A380 LOPA
here.
Well in this case my cynicism would appear to be justified and my arithmetic vindicated.
The A380 seat plan in your link does indeed purport to show 11-abreast, 18.5 inch "Cozy Suite" seating, but the accompanying video

shows that the seats in question are only
17.8" wide between armrests (the critical dimension).
I rest my case.
