Castres Olympique
Newcastle Falcons

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
Newcastle Falcons by 75+levelCastres Olympique by 75+

10.6% of runs finished in this bin — Castres Olympique by 13 to 17.

53 points is around the 54th percentile of the total — the middle run scored 51.

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.

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.

The fixture

Castres Olympique and Newcastle Falcons 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 Castres Olympique 0, Newcastle Falcons 1. Last 2020: Castres Olympique 17–26 Newcastle Falcons.

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.
