Eight runs in ten finished between 3 Lyon and 35 Leinster, half of them between 2 Leinster and 22 Leinster, with the middle run at 10 Leinster.
Those are gaps rather than scorelines. How much scoring the match produces is drawn separately — between 32 and 73 points in eight runs out of ten — so one bar covers many scores. The middle run above is 25-15 on a tight afternoon and 36-26 on an open one.
Why Leinster are favoured
How the model arrives at the chance of Leinster 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 Leinster, a bar to the left helps Lyon.
