1st annual offline tournament "Best Of The Best"

In other words, should I describe the events of the last day, including who goes where and attacks whom, or should I play until only the final battle remains and then specify which hero I attacked with which one? (I'm probably asking something very basic, but this is my first tournament, and I wouldn't want to do anything wrong).

P.S. I just want to do everything, save all the saves and descriptions in a separate folder, and start over...
