Metrics are measurements of content or actions against specific content or a user. Scores are calculated based on the underlying metric(s). Scoring can be accessed by clicking the pencil icon then navigating to Administration > Scoring.
Some metrics have the capability to be configured to only look at recent content or actions. Based on the screenshot below, the bookmarks metric only counts bookmarks that occurred within the last 180 days. By allowing you to set a number of days, newer content can score higher than older stale content.
Scores are made up of one or more metrics. Weight can be applied to the metrics to give more or less weight. In the below screenshot you can see the User Reputation is made up of 4 different metrics with the User Content Quality metric having the most weight.
Metrics can be removed or added to scores by clicking the 'Add metrics' link or selecting the metric to remove and then clicking the 'Remove' link.
When adding a metric, you can see a list of metrics to add and check the box next to each metric you wish to add, then click the 'Add Metrics' button.
Sample values display the highest 10 and the lowest 10 metric values. You can view the sample values under Scoring by selecting the score with the metric you wish to view the sample scores for, then selecting the metric and clicking the 'View sample values' link.
The next page will have tabs to show the users or content with the highest values, a tab to show the users with the lowest values and a tab to search for specific user values. The values listed are the normalized values between 0 and 100%. In this example screenshot, Erik has more likes than any other user therefore he is ranked 100.

Certain scores are user based and certain scores are content based. When adding metrics to these scores, note the differences of the metrics, such as the Bookmarks metric and the User Bookmarks metric. The Bookmarks metric measures the count of bookmarks against a user or a piece of content, whereas the User Bookmark would measure the count of bookmarks the user being scored made.
