Each figure is 5,000 simulations of this fixture. The score is where those runs are centred, not a likely scoreline — a rugby result is spread far too widely for any single one to be likely.

How the runs finished

Winning margin across 5,000 simulations of this fixture. Bars right of the centre are Samoa wins; the faded bars at each end hold everything beyond 75 points.

Eight runs in ten finished between 43 Scotland and 1 Scotland, with the middle run at 15 Scotland.

Those are gaps rather than scorelines. How much scoring the match produces is drawn separately — between 33 and 76 points in eight runs out of ten — so one bar covers many scores. The middle run above is 28-13 on a tight afternoon and 39-24 on an open one.

The 5 most recent meetings; the record above covers all 6. 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.
