So how can Hot Issue have only 95 sales on Circle but 2,504+ sales on Hanteo? (I'm confused)

Quote from Help1

I have read the "Ok, stupid need help: Gaon, Hanteo, Circle etc" thread but I am still confused.

Wikipedia says Hot Issue's 1st album Issue Maker released on 4/28/21 sold 95 units. Its source for this is Gaon/Circle chart, adding up day 1 sales (61) and day 2 sales (34) on the Retail Album chart.

https://circlechart.kr/page_ch…Gbn=day&yyyymmdd=20210428 - Issue Maker at #23, Sales: 61

https://circlechart.kr/page_ch…Gbn=day&yyyymmdd=20210429 - Issue Maker at #35, Sales: 34

It doesn't appear on the daily charts from 4/30 to 5/5. (The first week of sales would be 4/28 to 5/3)

However on Twitter, @koreansales_twt and @kpopggsuperior say 1st day sales on Hanteo for Issue Maker were 401 and additionally, 1st week Hanteo sales were 2,504. (Obviously, I have no way to verify this information, but I believe the accounts as they are dedicated to tracking sales.)

So how can one chart be counting 61 on day one while another counts 401, one of them counts a total of 95 while the other counts a total of over 2,500? It can't be the first time there is a big difference like this but I don't get why. Why does only a small percentage of the sales appear on Circle.

I can be wrong - but I don't think that you should use Retail Album chart but album chart. Gaon doesn't update numbers daily as Hanteo does. So usually we learn Gaon numbers later.

But I am not an expert in Korean chart, so I can be wrong

don't open my Hot Issue wounds...

I'm still not over their disbandment
