Each figure is 5,000 simulations of this fixture. The score is where those runs are centred, not a likely scoreline — a rugby result is spread far too widely for any single one to be likely.

Eight runs in ten finished between 20 Ospreys and 15 Cheetahs, with the middle run at 2 Ospreys.

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 21-19 on a tight afternoon and 31-29 on an open one.
