Your scoreline
New South Wales Waratahs
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+levelNew South Wales Waratahs by 75+

23.6% 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
New South Wales Waratahs 32.8%Stormers 64.7%average 2627

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

New South Wales Waratahs 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.

2 meetings New South Wales Waratahs 1, Stormers 1. Last 2018: New South Wales Waratahs 34–27 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.
