Eight runs in ten finished between 51 South Africa and 2 South Africa, with the middle run at 22 South Africa.

Those are gaps rather than scorelines. How much scoring the match produces is drawn separately — between 35 and 79 points in eight runs out of ten — so one bar covers many scores. The middle run above is 33-11 on a tight afternoon and 45-23 on an open one.

A dash under Competition means the record does not name one, which is common — most rows on file carry no competition. None of this feeds the forecast: both ratings already contain these results.
