Northampton Saints

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
Northampton Saints by 75+levelCardiff Blues by 75+

19.5% of runs finished in this bin — within 2 points either way.

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.

What the model says
Cardiff Blues 39.6%Northampton Saints 57.9%average 26–27

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 Cardiff Blues are not favoured

How the model arrives at the chance of Cardiff Blues 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 Cardiff Blues, a bar to the left helps Northampton Saints.

The fixture

Cardiff Blues and Northampton Saints 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 — Cardiff Blues 0, Northampton Saints 1. Last 2026: Northampton Saints 28–12 Cardiff Blues.

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.
