How the runs finished
Winning margin across 5,000 simulations of this fixture. Bars right of the centre are Exeter Chiefs wins; the faded bars at each end hold everything beyond 75 points.
Margin percentiles
Eight runs in ten finished between 20 Leinster and 14 Exeter Chiefs, with the middle run at level.
Those are gaps rather than scorelines. How much scoring the match produces is drawn separately — between 30 and 70 points in eight runs out of ten — so one bar covers many scores. The middle run above is 19-19 on a tight afternoon and 30-30 on an open one.
