Scottish Premiership REVIEW 20 Sep 2026: Rangers win at Celtic Park and every one of our nine models had it wrong

Our model made Celtic favourites for the Glasgow derby and the afternoon took it apart. The consensus settled at 48 per cent Celtic, 29 per cent the draw and 24 per cent Rangers, and all nine of the models behind it leaned the same way, the Elo rating most emphatically of all at 68 per cent for the home side.
