 | Metric | Calculation | Description | 
 | --- | --- | --- |
-| **Total Time** | Sum of `lead_times` | The total time spent annotating during the selected time frame. This is calculated based on annotations that meet the criteria for **Submitted Annotations** (see below). <br /><br />The total time does not include time spent on annotations that have not been submitted and/or updated. For example, it does not include time spent on drafts or time spent on skipped annotations. <br /><br />However, if they return to an annotation draft or a previously skipped annotation, then their earlier time spent on the annotation is included when calculating their total annotation time.  | 
+| **Total Time** | Sum of `lead_times` | The total time spent annotating during the selected time frame. This is calculated based on annotations that meet the criteria for **Submitted Annotations** (see below). <br /><br />All annotations have a `lead_time`. The lead time reflects how much time a user spent labeling from the moment the task was opened until they click **Submit** or **Update**. This includes idle time. <br /><br />The total time does not include time spent on annotations that have not been submitted and/or updated. For example, it does not include time spent on drafts or time spent on skipped annotations. <br /><br />However, if they return to an annotation draft or a previously skipped annotation, then their earlier time spent on the annotation is included when calculating their total annotation time.  | 
 | **Submitted Annotations** | Sum of `submitted_or_reviewed` | The total number of annotations the user submitted during the selected time frame. <br /><br />This includes annotations that have been submitted and updated. <br /><br />It does not include annotations that have been skipped. It also does not include annotations that were submitted and have since been rejected by a reviewer. However, if the annotator updates a rejected annotation and that fix is then accepted by a reviewer, the corrected annotation is included within their Submitted Annotation count. <br /><br />Note that each annotation is only included in their submitted count once. Label Studio does not count the same annotation twice based if it is later updated. | 
 | **Total Time (Median)** | Sum of `submitted_or_reviewed` * the median of `lead_times` | The number of submitted annotations multiplied by their median annotation time. | 
 | **Time per Annotation (Median)** | Median of `lead_times` | The median time they spent on each submitted annotation. | 
 | **Time per Annotation (Average)** | Average of `lead_times` | The average time they spent on each submitted annotation. | 
+| **Performance Score** | Calculated from reviewer actions | The Performance Score reflects the overall performance of annotators in terms of review actions (**Accept**, **Reject**, **Fix+Accept**). <br /><br />The calculation is as follows:<ul><li>Each annotation review action (**Accept**, **Reject**, **Fix+Accept**) contributes to the score.</li><li>The score is calculated by summing the scores of all review actions and dividing by the total number of review actions. For example: </li><ul><li>If an annotation is rejected twice and then accepted once, the Performance Score would be (0 + 0 + 1) / 3 = 33%.</li><li>If an annotation is rejected once and then fixed+accepted with a score of 42%, the Performance Score would be (0 + 0.42) / 2 = 21%.</li></ul></ul> |
