I'm not sure I can pip you tbh. It was in my hands until you beat me. However, once I lost I was relying on a slip up which never came.
I have 3 games left. From 17 games I have 12 wins, 3 draws 2 losses = 39 points. I can only reach 48 points (even if I win all).
Whilst you haven't lost a game. You are 15 wins and 5 draws (I think?) = 50 points.
I believe the title is yours my friend. Well deserved too.
