+Note that the Avg_MHz column reflects the total number of cycles executed
+divided by the measurement interval. If the %Busy column is 100%,
+then the processor was running at that speed the entire interval.
+The Avg_MHz multiplied by the %Busy results in the Bzy_MHz --
+which is the average frequency while the processor was executing --
+not including any non-busy idle time.
