RING_BUFFER_SCHEDULER_MONITOR reporting over 100% ProcessUtilization

I am using RING_BUFFER_SCHEDULER_MONITOR to get cpu history for the server. For some reason on our new intel box (system info below) we are experiencing above 100% (in the xml below it shows 129) ProcessUtilization. Is there any correction I need to be applying to this value or why would it be above 100 ever?

Thank you
