Your scoreline
Cardiff Blues
Sharks

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
Sharks by 75+levelCardiff Blues by 75+

18.2% of runs finished in this bin — Cardiff Blues by 3 to 7.

50 points is around the 55th percentile of the total — the middle run scored 48.

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 64.1%Sharks 33.4%average 2623

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

Cardiff Blues and Sharks 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 Cardiff Blues 3, Sharks 2. Last 2026: Sharks 21–15 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.
