Eight runs in ten finished between 2 Australia and 51 Australia, half of them between 8 Australia and 37 Australia, with the middle run at 21 Australia.

Those are gaps rather than scorelines. How much scoring the match produces is drawn separately — between 34 and 78 points in eight runs out of ten — so one bar covers many scores. The middle run above is 32-11 on a tight afternoon and 43-22 on an open one.

Why Australia are favoured

How the model arrives at the chance of Australia winning. It starts at an even 50%, and each line below adds to that or takes from it, in percentage points (pp): a bar to the right helps Australia, a bar to the left helps Portugal.
