Mmr problem about APAC Battlegrounds

I think there is still problem about mmr, so there are users in top rank using wrong mmr.
Top 1 in APAC user named “마리에타” gets 100 point when he is 15.7k, which is top rank of the APAC area.
Its impossible to get 100 points. Even if we get most high points, we should get 75 points for top rank. Therefore I conclude that there still is mmr problem for some accounts. plz answer me because i feel its not fair game.
you should give all players sense of accomplishment and fairness.
I will wait for answer. Thank you
