If its 20k just for one day her projections will be something like 40 to 45k I would imagine.
However its been months since I followed sales so I'm not really sure how much things are selling these days. So in turn have no idea if that's now good or bad.
Her new sound isn't that much beloved in Europe, hence the sicnificant lower review ratings in the UK.
Also lack of promo by now but with Glastonbury and BBC radio 1 promo, Ultra will do quite good.
And if she "only" sells 600k it would be quite a success, probably only Ella Henderson and Emeli Sande can sell more with a 2014 release.
