      JEP 520: JFR Method Timing & Tracing added capabilities to time individual methods, but the view representation and the data can be confusing:

      - The event description should state that the measured values are approximations and that not just CPU time is measured.
       The measured time may become 0 due to a low-resolution clock. It's better not to include those values when determining the minimum value.
      - Ensure that the minimum and maximum values are reasonable when compared to the average.
      - Use "Minimum" and "Maximum" instead of "Min." and "Max." in the method-timing view to create some space between columns.
