        Analyze estimate with anything over 49% results in automatic
compute. DBMS_STATS estimate option, will estimate to the percentage you
request.  =20

Without looking, doesn't estimate_percent >50 cause a compute?  I
remember
it did on ANALYZE, but I don't remember with DBMS_STATS... Rich

Don't feel too bad about this one. IMHO, cascade=3D>FALSE (the default) =
is
the
right choice, especially if you use estimate_percent of less than 100%.
Then
follow with an explicit gather_index_stats with a full compute. And any
histograms also with a full compute.
