What have the number of lines in the plan and the predicates section got to do 
with dynamic sampling? Are you saying dynamic sampling is a bad thing? It seems 
like an excellent feature to me.

AARGH!

What you do when DBMS_XPLAN.DISPLAY_CURSOR shows a 190 line Plan with 205 entries in the 
Predicates section  and then adds "dynamic sampling used".

Just venting my frustration.
