Better explanation about "% privileged utility"

Hi, I noted in perfmon a counter called "% privileged utility".
Looking at task manager "Show kernel times", boths counters seems more related than "% privileged time".

I don't found some official resources about this metric. Someone knows it?
The first time I see was on this thread: https://social.technet.microsoft.com/Forums/en-US/57552851-5268-4c9c-8688-432c9fad1d8d/privileged-time-and-privileged-utility-processor-time-and-processor-utility-user-time?forum=winserver8gen

My need to understand this is what the user on forum says: Task manager "show kernel times" is showing privileged utility or % privileged time?
IN my tests, I noted that perfmon % privileged have a big difference from taskmgr.
But, privileged utility seems more close to it.

Hi,
According to my research, there is very little relevant information.
Privileged Utility is the amount of work a processor is completing while executing in privileged mode, as a percentage of the amount of work the processor could complete if it were running at its nominal performance and never idle. On some processors, Privileged Utility may exceed 100%.
For your reference:
