we haven't done a RACE in a while. It was originally concieved to allow multiple games to take place at once, to take advantage of the asynchronous nature of codex. So, Yes, it was Round Robin, but you are assigned all your matches right from the beginning, and then complete them as you and your opponent are able. Some players might finish 8 matches in a week, and others might take longer. EricF has implemented various measures to try and better handle the disparity in play speed. I dunno how successful he thinks any of those measures were, but they were all fun in my opinion. The RACE tournaments always felt really fast and hectic, especially compared to Swiss.
