You might want to check syslog on each LPAR and see what might be happening that correlates with the spike in performance your stats are reporting.
For example, what if your automation package is issuing a command like D GRS,C at hourly intervals? What if that automation was written to issue the command at exactly the same time on every LPAR in the sysplex? Just a thought....
