Eight runs in ten finished between 9 Northampton Saints and 29 Leinster, half of them between 2 Northampton Saints and 17 Leinster, with the middle run at 6 Leinster.

Those are gaps rather than scorelines. How much scoring the match produces is drawn separately — between 31 and 72 points in eight runs out of ten — so one bar covers many scores. The middle run above is 23-17 on a tight afternoon and 33-27 on an open one.
