What are you referring to - a manual? office gossip? something else?
The problem I have is that people can explain things quickly but I can only comprehend slowly.

I Googled "updatable catalog tables" and the first entry (which was for DB2/Linux but that should not matter) has this on the first page:
I did not investigate further but you can if you need to (unless you are an admin then you probably do not).
SYSSTAT views are updatable catalog views that are found in the SYSSTAT schema. The updatable views contain statistical information that is used by the optimizer. The values in some columns in these views can be changed to test performance. (Before changing any statistics, it is recommended that the RUNSTATS command be invoked so that all the statistics reflect the current state.)
