Well, it was 1.657 last week. 1.68 would mean she sold more than 20k and should be in top 40. I guess it's an estimated number. Still, 1.68 is good. Next weeks WW numbers will be better. She's TOP 20 on iTunes Norway(big market), TOP 15 on iTunes Australia and TOP 10 on iTunes New Zealand. In all those countries she was around #350 last week.
I feel people forget that there is no way to measure WW sales accurately.
Countable figures offer only the minimum, and shipped figures offer the maximum. The latter is what the industry goes on because you have to assume that the label is aware of demand, so is supplying units to meet it. It's flawed, but one would presume that they wouldn't willingly waste money manufacturing/shelving likely unsold albums.
