Research direction

Examine the current Sentinel dashboard implementation to understand how statistics are currently displayed. Check the backend API that provides metric data to the frontend. Look for existing percentile calculations in the codebase. A good starting point would be the dashboard frontend code and the backend controller that serves metric data. Consider adding new API endpoints for percentile data and updating the frontend chart components to display them.
