I don't think we should use the 2011/2012 Rihanna-Adele scenario as some point of comparison at all tho...

Back then, Adele didn't have the hype of a 30MWW sold album behind her like she does right now. Also, Rihanna wasn't doing this weird ass 'little by little'-silent treatment kind of era. Her ship was tighter then. Then you have to consider the overall decline of album sales. Yes, they can co-exist but the dynamics are not even remotely the same.
Rih could maybe still execute this era decently in the long run but all this worry about #1 albums, first week sales, promo. She still outchea recording the album 3 singles and music videos in. The era is so past that point

. Be happy when you get the album then log off of ATRL because it will be a mess.
