How the runs finished
Winning margin across 5,000 simulations of this fixture. Bars right of the centre are Australia wins; the faded bars at each end hold everything beyond 75 points.
Margin percentiles
Eight runs in ten finished between 2 Australia and 51 Australia, with the middle run at 21 Australia.
Those are gaps rather than scorelines. How much scoring the match produces is drawn separately — between 33 and 77 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
Starting from an even match and adding what the model reads, in percentage points of win probability. Positive favours Australia, negative favours USA.

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.
