How long has it been since the reset?
There might still be wrong ranked peole even if it is already a bit longer since the reset. I am at about 40 percent atm and was around 80-90 before(more like 80). And because I only play 3 matches a day for daily until monthly complete I only started to play 3 matches since start of this month (x10 = only 30 matches after reset). So it can take some time. Of course most that played a lot should already be ranked correctly.
