Set a scoreline and see where it sits among the 5,000 simulated runs behind this fixture. Ratings as at 2026-08-23.

Your scoreline
Samoa
USA

The steppers skip 1, 2 and 4. Points come in fives, threes and twos with a conversion needing a try in front of it, so no match has ever finished on any of them.

Where that lands
USA by 75+levelSamoa by 75+

9.6% of runs finished in this bin — Samoa by 8 to 12.

51 points is around the 56th percentile of the total — the middle run scored 48.

Those two figures are separate readings and are not multiplied together. The simulation draws the gap and the amount of scoring independently, so one bar of the histogram covers many scorelines and the payload holds nothing about which of them came up with which gap.

What the model says
Samoa 60.8%USA 36.3%average 2921

Your pick agrees with the model on the winner. Nothing here scores that. The model’s gap is an average over both winners and yours is one afternoon, so the two are different kinds of number rather than one being right. How the model works.

Why Samoa are favoured

The fixture

Samoa and USA have no fixture on the published schedule, so there is no ground, no kick-off forecast and no team sheet to put beside this. The prediction itself does not need any of them.

4 meetings Samoa 3, USA 1. Last 2024: USA 13–18 Samoa.

None of this reaches the model. Weather is not a feature, team selection is not a feature and the record is already inside both ratings, so the probability above does not move because any of it changed.
