Cause I wanted you to check and let me know
It is all bottom charting. Pure sales are always front loaded. Billboard, Gaon, Hanteo, take whichever you want and compare. 80-90% of sales happen during first week. You keep saying "logic logic logic" but somehow missing the biggest one there. BP had better streams, hence better units, hence longer charting, we've already established that. Nothing suggests they kept selling a lot of albums on their 10+ weeks. Absolutely nothing, no logic behind that claim.
So you admit you literally just lied and hoped that the data you were making up existed? lol.
What I was able to find, in the first 5 weeks, BP did 120k pure sales, compared to 75k pure in the first week. That's 63 percent of the sales being in the first week, with more sales after(data unknown as far as my searching ability), So your claim that 80-90 percent of sales happen during the first week is another lie you're just hoping to be true.
The sales for Twice may have been more front loaded for all we know.
You say no logic behind that claim, but there you go. You've been proven wrong again.
