That is adjusting for pure consumption. There are no imaginary multipliers or any "what-ifs" involved. The market isn't even the same from week-to-week, let alone year-to-year. Just in 2015, we've had a WW #1 with only 280k sold and one with 5.8M sold. Why would we assume those #1s are equal?

I don't see how you can assume that 21 would have sold 27M copies WW in just the U.S. in one year when fewer people than that have consumed it from 2011 to 2015 in the U.S.
