Cardiff Blues

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
Cardiff Blues by 75+levelOspreys by 75+

18.4% of runs finished in this bin — within 2 points either way.

47 points is around the 57th percentile of the total — the middle run scored 44.

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
Ospreys 59.1%Cardiff Blues 38.4%average 24–22

Your pick agrees with the model on the more likely winner, Ospreys. Nothing here scores any of it. 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 Ospreys are favoured

How the model arrives at the chance of Ospreys winning. It starts at an even 50%, and each line below adds to that or takes from it, in percentage points (pp): a bar to the right helps Ospreys, a bar to the left helps Cardiff Blues.

The fixture

Ospreys and Cardiff Blues 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.

22 meetings — Ospreys 15, Cardiff Blues 6, 1 drawn. Last 2026: Cardiff Blues 24–21 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.
