Flow found an issue with how New work, Legacy refactor, Help others, and Churn were being calculated in the Snapshot report. These four metrics, collectively known as the focus metrics, were being incorrectly calculated for group work. In some cases, commits would be duplicated for pair and group commits. This skewed the metrics.
This issue is fixed, and all historical metrics are updated.
The impact of this should be small and the biggest change you might see is a decrease in the total number of commits displayed in the Snapshot report. No metrics in other reports are affected.
