Eight runs in ten finished between 12 Ulster and 27 Sharks, with the middle run at 1 Sharks.

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 19-18 on a tight afternoon and 30-29 on an open one.
