OK, so you were printing the kernel.pct.cpu.user derived metric.

See, this time you were printing the kernel.percpu.cpu.user metric,
not the derived one.  If you do the same $PCP_DERIVED_CONFIG=...
setting and print kernel.pct.cpu.user, you'll get the same kinds of
values as you did in the live case.
