Based on the current rate they will win the league by around 30 points. So in 10 games time they could afford to lose every game after that and they’d still win the title. If they do continue doing what they are doing I reckon it’ll be mathematically done mid March at the latest.
Although it was a great achievement Arsenal got 12 draws during that season and won it by 11 points. City are only 9 wins behind their overall win total!
