Your scoreline
Tonga
Wales

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
Wales by 75+levelTonga by 75+

8.5% of runs finished in this bin — Wales by 18 to 22.

54 points is around the 52nd percentile of the total — the middle run scored 53.

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
Tonga 10.5%Wales 88.5%average 1638

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 Tonga are not favoured

Starting from an even match and adding what the model reads, in percentage points of win probability. Positive favours Tonga, negative favours Wales.

The fixture

Tonga and Wales 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 Tonga 0, Wales 4. Last 2018: Wales 74–24 Tonga.

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.
