By the way statspack does not gather ACCESS_PREDICATES neither
FILTER_PREDICATES, checking statspack.snap code it states this
insert into stats$sql_plan
......................
, 0 -- should be max(sp.access_predicates) (2254299)
, 0 -- should be max(sp.filter_predicates)
checked this in 9.2.0.8, I understand that there were bugs regarding these
two fileds inv $sql_plan previous version 9.2.0.6 but in 9.2.0.8?
2254299 doesnt seem a bug number
Cheers

Level 6 is required to get execution plans.
Level 7 also included segment stats:
From spdoc.txt:
This level includes all statistics gathered in the lower level(s),
and additionally gathers the performance data on highly used segments.
