There shouldn't be a question as to which numbers to use. At the end of the day, it is which source is official and which isn't. Try using the International Federation of the Phonographic Industry (IFPI) or MediaTraffic on a school report and see which one your professor will accept as a credible source.
The gurs needs to stop playing hot potato with her numbers and find some common ground.
And I'm just trying to keep the peace and not make the Hive seem like a bunch of overestimating fiends. She has already outsold all the other girls no matter what number is in the title! But I understand the need for that exact figure.
