1. "Perfectly" is a great word to describe something if it went as planned without any problems. It's somewhat of an exaggeration, but if something goes well without much resistance, it's almost as if it was "perfect". People will understand you're trying to explain the great results of what happened. Often times, the word perfect is used to exclaim agreement and approval that something is really good, i.e. "sounds perfect!"
   
   2. "Really well" has less of a punch as "perfect", but it's a great way to explain that you had a similarly good outcome, and you had little to no problems.
