The statistics job (GATHER_STATS_JOB) is run at night (Mon-Fri,10pm-6am and Sat,Sun ). It will gather Statistics on the tables with "stale" statistics for all schema(s). (including the sys schema).

Why would Statistics not be gathered by the statistics job for a table which has many insert(s) and update(s)?
