Sql Maint Plans and DBCCs

I have set up a Database Maintenance Plan to only do DBCCs. Under the Integrity Tab I have checked the box 'Check Database Integrity'. I have 'included Indexes' and I have checked 'Attempt to Repair Any Minor Problems'. When the Plan is scheduled to run, it runs successfully. The database that I am running against is 26 gig in size and the Plan finishes in 1 sec. I don’t have a real good fuzzy felling that this is doing a DBCC CheckDB. I have been told that MS has improved performance for many DBCCs but I'm not convinced they have improved it this much. Am I being overly paranoid or am I not doing something right?

Thanks in advance,
