Has always been the case here. For example we took a POR outage on the
weekend, and since then the numbers show that none of the 5 systems sharing
the MCAT have hit rates above 50%.
I have always put it down to the following from "Managing Catalogs", and
basically ignored it - maybe I'll also try and get some trace data and
chase it a bit further;

"The master catalog will always be searched for data set names that do not
have an alias to a user catalog. For example, non-existent data set names
and SMS-managed temporary data sets are not cataloged so all searches for
them would show up as a "miss" of the master catalog cache. This may cause
the hit ratio for the master catalog cache to appear lower than expected."
