Your scoreline
Clermont Auvergne
Ospreys

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
Ospreys by 75+levelClermont Auvergne by 75+

10.9% of runs finished in this bin — Clermont Auvergne by 13 to 17.

50 points is around the 52nd percentile of the total — the middle run scored 49.

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
Clermont Auvergne 78.2%Ospreys 19.3%average 3317

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

Clermont Auvergne and Ospreys 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 Clermont Auvergne 3, Ospreys 1. Last 2018: Clermont Auvergne 24–7 Ospreys.

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.
