Saving time on nightly table rebuilds

We have several large tables that are rebuilt each evening into a new database. The size does not vary dramatically week to week, so we use the dbms_stats package to import and export the statistics on these tables each night, and only gather the statistics once per week. The code below does the weekly analyze; reset_table_stats is used as a customer deletes and gathers statistics using dbms_stats package. This script was tested on Oracle
spool /oemmaint/qa_out/fcra_analyze.out2
delete from analyzedb.stat_table where statid in
exec analyzedb.reset_table_stats('APPTMGR','ASSOCIATION_LOA')
exec analyzedb.reset_table_stats('APPTMGR','ASSOCIATION')
exec analyzedb.reset_table_stats('LICMGR','ENTITY_STATE_LICENSE_LOA')
exec analyzedb.reset_table_stats('LICMGR','ENTITY_STATE_LICENSE_CLASS')
delete from analyzedb.stat_table@&DESTDB where statid in
insert into analyzedb.stat_table@&DESTDB
