Eight runs in ten finished between 19 Stormers and 15 Bayonne, half of them between 10 Stormers and 5 Bayonne, with the middle run at 2 Stormers.
Those are gaps rather than scorelines. How much scoring the match produces is drawn separately — between 32 and 72 points in eight runs out of ten — so one bar covers many scores. The middle run above is 21-19 on a tight afternoon and 32-30 on an open one.
