How are the rows on A380-s supposed to be numbered? The Airbus demonstrator plane 007 is known to have row 84. What are the plans of the airline customers?

Especially because the numbers on 747 upper deck are pretty inconsistent.

Looking at seatguru.com

Those have maindeck last row 57 or so, upperdeck 60 to 69.

One Air NZ 747 has rows 1-3 in nose, then 7 to 14 on upper deck, then starting with 15 on main deck, to 60. Another has rows 1-7 and 10-15 starting from nose, then 16-20 and 23-27 on upper deck, then starting at 31 on main deck, last row 68.

So, how are the row numbers on the other 747 operators?
