What are the units in output of tmctl virtual_server_cpu_stat?

I have a user who is concerned about our F5 CPU consumption. Looking at the output of tmctl virtual_server_cpu_stat, we see some figures exceeding 200...

 tmctl virtual_server_cpu_stat
...
/Common/xyz-VS 2143543782237728      234      250      248
/Common/abc-VS 700776669167712       90       90       92

show ltm virtual shows cpu a only 2%:

 tmsh show ltm virtual xyz-VS
...
CPU Usage Ratio (%)
   Last 5 Seconds                             2
   Last 1 Minute                              3
   Last 5 Minutes                             2

My assertion is that the output of tmctl virtual_server_cpu_stat is load average, not cpu%. This makes sense, the numbers from tmctl virtual_server_cpu_stat are about equal to the number of concurrent connections to the virtual.

Is this assertion correct?

Thanks w
