The metrics of Buchholz and Berger-Sonneborn (often truncated to just Berger) are popular in chess, draughts, go and some other round-robin competition. Read more about them on the Glossary page.

In this table the metrics are displayed in per/game basis (actually value divided by the number of games played). The Buchholz metric indicates how strong has been the field the team has played so far. At the end of the season it essentially compares the strength of teams' divisions because that's where the biggest weight of their opposition comes from. The Berger stat effectively shows how well the team fared against the top and the bottom opposition respectively, the value above the 'expected' one indicates the team did better than expected against the better team and poorer against the bottom feeders and vice versa.

We consider that last relation an indication of how the team roster was managed during the year. In case when the Berger is better than expected, it shows that the coach used the roster worse than possible, because the team was not concentrated enough against the lesser ones. On the other hand, when the team excels against the lower part of the standings, it shows that the coach squeezed the maximum and beyond from the given roster which was not good enough to compete against the top of the league.

The standings are available per season. During the current season we also display the 'Remaining Schedule Strength' which shows how strong is the remaining opposition for the team.

The metrics are generated from the box scores and are available from year 1987 on.

? Buchholz and Berger-Sonneborn coefficients for teams

The Buchholz metric indicates how strong has been the field the team has played so far. At the end of the season it essentially compares the strength of teams' divisions because that's where the biggest weight of their opposition comes from. The Berger stat effectively shows how well the team fared against the top and the bottom opposition respectively, the value above the 'expected' one indicates the team did better than expected against the better team and poorer against the bottom feeders and vice versa. The Remaining Strength metric is essentially the "Buchholz" of the remaining schedule. The metric is only calculated for Regular Season.
