Your scoreline
Russia
Samoa

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
Samoa by 75+levelRussia by 75+

8.8% of runs finished in this bin — Samoa by 18 to 22.

56 points is around the 52nd percentile of the total — the middle run scored 55.

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
Russia 18.1%Samoa 80.9%average 1937

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 Russia are not favoured

The fixture

Russia and Samoa 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.

1 meetings Russia 0, Samoa 1. Last 2019: Russia 9–34 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.
