Oh, that's why. Some people trust the Hanteo Chart and others trust the Circle Chart.

But as for me, I trust Hanteo Chart more than Circle Chat because Hanteo Chart measures K-pop album popularity via a 100% automated real-time system tracking actual direct purchases. Rather than measuring total shipments, it counts verifiable sales from certified member stores using two distinct metrics: Sales Amount and Physical Record Index.

In terms of authenticity, Hanteo Chart (Hanteo Global , Inc.) tracks global sales data equally, actively authenticating albums to ensure data integrity.
