Could our average session duration (~6 minutes) be inflated compared to Google Analytics (1 minute) due to the inclusion of server-side or system-level events that are stretching the duration between the first and last event, but are not actual user interactions?
If so, what event property is the most reliable way to filter a session query to include only client-side, user-driven events (excluding server-side, internal, or bot activity)? Is it $source, $device_type, or another property?
