Rorie,
CIF_IMAX is a synthesis of the data found in the various CIF_I* tables. If you have any question as to whether the contents of this table are right or wrong, just regenerate it using report RCIFIMAX. Regeneration generally only takes a few minutes at most.
In general, if you perform the standard recommended reorganization activities periodically, you can pretty much ignore the contents of these technical tables.
I am curious why you are questioning the contents of this table. Is it causing some kind of problem?
Best Regards,
