As for Chris numbers, they are lukewarm but considering all the bad press he has had since RiRi and all his legal issues, The number's aren't that bad but Chris has fallen really far. Since he hit RiRi in 2009, he has Yet to go Platinum yet this is his 4th album since that. Before that he had 2 Multi-Platinum albums and was headed to being basically in Usher's lane. Had the RiRi incident didn't happen, Chris could of been headed to 4x Platinum maybe even 5x Platinum. It's clear that incident is still affecting his sales. Same with KanYe and the Taylor Swift, you can litterally trace his sales dropping off from that point:
Chris Brown - 2x Platinum
Exclusive - 2x Platinum
Graffti - 350k
F.A.M.E. 750k
Fortune 500k
X - Will Tap out at 350-400k
