Explain plan for set table - forum topic by abin

Hi,
 
I have a requirement to convert around 50 tables into multiset from set. I am trying to get the tradeofff of keeping the table as set against perfomance of inserting recs into it. I did an explain plan on insert statmenets for a table defined as set and then altered it as set. Both insert gives me same explain plan. I was expecting some additional steps in plan for set table because of system level duplicate check.
 
So my question does explain plan shows the additional steps involved in syetm level duplicate check performed for a set table.
