Your scoreline
Harlequins
Stormers

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
Stormers by 75+levelHarlequins by 75+

16.1% of runs finished in this bin — Harlequins by 3 to 7.

49 points is around the 54th 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
Harlequins 64.1%Stormers 33.4%average 2722

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

Harlequins and Stormers 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.

3 meetings Harlequins 2, Stormers 1. Last 2026: Harlequins 61–10 Stormers.

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.
