HDD are always wrong and sometimes are nice to some people.
And yet they put her 3 and with the others even higher
Twilight 150-170k
Glee 140-160k
Which only makes her sales even seem worse

.
KGB sold like 70-80k and it was a GH album, KGB wasn't a bigger hit than NMT since both sold almost the same first week (about 70k+) and than dropped like a rock, KGB just had more luck.
So this is not good for her.
I hope for her sake that her WW sales will at least pass the 200k mark, or at least the 150k cuz' I dunno what to expect anymore.
