qm would have the same issue, but there, we don't even output a line for
"cpu:" ;)

IMHO, the average of the CPU usage across the whole uptime is not what
most people would expect this value to be. Maybe we should just remove
the line from the output like in qm (technically a breaking change) or
maybe query the CPU stats twice with a small time window in between?

No matter what approach we go for, the behavior of qm and pct should be
made consistent here (if no good reason against it pops up).
