This player has been a suspected toggler for a long time. You will see some rounds he has low hskr but high acc and others he has low acc & but high hskr [ i.e. 9% hskr & 24% acc]. His latest reports show an average of 14% accuracy but 30% hskr. His stats are very consistent in this regard.
Also, there are a sprinkling of 40% & 60% hskr with the AEK, M4, etc through out the BRs linked here>>>
