Is/Has anyone refiled 2010, 2011?

As I said in the other thread, we are refiling 2010 and 2011 (yes yes, I know, we should have done it before!). Has anyone refiled these (our adoption didn't finalize till 2012 and our son was born early 2012 so we got placement last year too)? Do you know if the auditing etc. has been as hard as people who filed these the first time round? Hubby said that he read something like 80% were audited and only a tiny percentage had even minor paperwork problems but I'm wondering if they have now learned their lesson!
