Understanding the Loop Dashboard metrics and indicators.
Trends are calculated by comparing the current period's metrics to the previous period of the same length. The overall trend for a loop is the simple average of all metrics visible to the selected stakeholder's view.
Some metrics are "inverse" meaning lower values are better (e.g., error rates, response times, crash rates). For these metrics, a decrease is shown as an improvement (green) rather than a decline.
When you see "No prior data", it means this is the first period being measured and there's nothing to compare against yet. Trends will appear once enough historical data has been collected.
