Eight runs in ten finished between 28 Tonga and 15 Romania, with the middle run at 1 Tonga.

Those are gaps rather than scorelines. How much scoring the match produces is drawn separately — between 31 and 73 points in eight runs out of ten — so one bar covers many scores. The middle run above is 21-20 on a tight afternoon and 31-30 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.
