Eight runs in ten finished between 1 Japan and 49 Japan, half of them between 7 Japan and 34 Japan, with the middle run at 19 Japan.

Those are gaps rather than scorelines. How much scoring the match produces is drawn separately — between 32 and 76 points in eight runs out of ten — so one bar covers many scores. The middle run above is 30-11 on a tight afternoon and 41-22 on an open one.

Why Japan are favoured

How the model arrives at the chance of Japan 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 Japan, a bar to the left helps Uruguay.
