How the runs finished
Winning margin across 5,000 simulations of this fixture. Bars right of the centre are Japan wins; the faded bars at each end hold everything beyond 75 points.
Margin percentiles
Eight runs in ten finished between 1 Japan and 51 Japan, with the middle run at 21 Japan.
Those are gaps rather than scorelines. How much scoring the match produces is drawn separately — between 32 and 75 points in eight runs out of ten — so one bar covers many scores. The middle run above is 31-10 on a tight afternoon and 43-22 on an open one.
Why Japan are favoured

A dash under Competition means the record does not name one, which is common — most rows on file carry no competition. None of this feeds the forecast: both ratings already contain these results.
