They come from the getrusage() system call.

Current is an rusage() lookup during processing of the manager report.
That will include CPU consumption from processing the request and
generating the report.

The historic averages are calculated from polling Squid does in the
background every 60 seconds. When there may or may not be any request
processing going on.
