 When we describe GitLab analytics, we use the following terms:
 
-- **Cycle time:** The duration of only the execution work alone. Often displayed in combination with "lead time," which is longer. GitLab measures cycle time from issue first merge request creation to issue close. This approach underestimates lead time because merge request creation is always later than commit time. GitLab displays cycle time in [group-level Value Stream Analytics](../group/value_stream_analytics/index.md).
+- **Cycle time:** The duration of only the execution work. Cycle time is often displayed in combination with the lead time, which is longer than the cycle time. GitLab measures cycle time from the earliest commit of a [linked issue's merge request](../project/issues/crosslinking_issues.md) to when that issue is closed. The cycle time approach underestimates the lead time because merge request creation is always later than commit time. GitLab displays cycle time in [group-level Value Stream Analytics](../group/value_stream_analytics/index.md) and [project-level Value Stream Analytics](../analytics/value_stream_analytics.md).
 - **Deploys:** The total number of successful deployments to production in the given time frame (across all applicable projects). GitLab displays deploys in [group-level Value Stream Analytics](../group/value_stream_analytics/index.md) and [project-level Value Stream Analytics](value_stream_analytics.md).
