Your scoreline

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+levelBulls by 75+

10.7% of runs finished in this bin — Bulls by 13 to 17.

48 points is around the 53rd percentile of the total — the middle run scored 47.

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
Bulls 81.4%Ospreys 16.1%average 31–17

That is the model’s own average scoreline. 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 Bulls are favoured

How the model arrives at the chance of Bulls 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 Bulls, a bar to the left helps Ospreys.

The fixture

Bulls 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.

5 meetings — Bulls 5, Ospreys 0. Last 2025: Bulls 53–40 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.
