+## Understanding the `last_activity_at` calculation
+
+{% note %}
+
+**Note:** This data is in public beta and subject to change.
+
+{% endnote %}
+
+To align the `last_activity_at` data point with _actual usage_, the system returns the timestamp of a user's most recent interaction with Copilot functionality. These interactions are:
+
+* Receiving a code suggestion in an IDE
+* Chatting with Copilot Chat in an IDE
+{%- ifversion ghec %}
+* Creating or updating a knowledge base
+* Creating a pull request summary
+* Interacting with Copilot Chat on GitHub.com
+{%- endif %}
+* Interacting with Copilot on a mobile device
+* Interacting with Copilot Chat for CLI
+
+The `last_activity_at` date is consistent across the CSV generated via `Get Report` in Copilot Access settings as well as through {% data variables.product.prodname_dotcom %}'s REST API. The events which are tracked come from both client, and server-side telemetry. This allows the timestamp to be durable in the event that network conditions would impact client-telemetry.
