Where the 1.8M sales of G-idle went ???????

Please explain to me

Before G-idle comeback Cube announced 1.8M pre-order for their album

Kpop fans were hyping G-idle for being the only gg with "no fraudulent" sales cuz they were the only one who didn't saw a drop in sales this year.

and even recently i saw people commenting how G-idle was the best selling GG this year.

But today while commenting on other thread i used Circle yearly album chart as data in my comment

and while scrolling and looking at every groups sales i saw the sales of G-idle for "2"

considering i'm not following G-idle sales i expected them to see them really high, but i was surprise to see them at #18

so i looked at the number of sales for their album and saw that "2" sold 1.1M copies.

Can someone explain to me where the 700K other album went ?

And how much "2" really sales 1.8M or 1.1M ??

Update :

I went on Hanteo to see how much sales the album have and see if it's inferior

cuz i remember in the past Gaon/circle sales were always higher than Hanteo sales

On Hanteo "2" sold 1.5M album

So now i Have a new question

From what i understood from my own research

Circle tracks all the album that the distributor sent to retailer

while Hanteo track all the sales from retailer to customer directly

( and only sales from retailer who are affiliated to Hanteo)

Based on this observation

can you explain to me how retailers can sold more album than the number of album that distributor sent to these retailers ???

Quote from haricot

1.1M + 0.6M= 1.7M (circle chart 2024), so not far from 1.8M

Oh thanks i didn't know they released a poca version

i find this pretty stupid to separate the sales of each version of the album

cuz at the end it's the exact same album, it just makes it confusing
