All groups which have at least one completed game have had their standings updated in the main post. The first group (El Burro) has finished and ended in a tie both for points and for games won.
If no other groups finish in this way, I'll put both players through to the final and make it an 8-man final game. If another group finishes tied on both points and games won, then I'll use the least number of rounds taken to win the contestants respective winning games as a tie-breaker. If this is also tied (!!), I'll just use random.org.
If anyone has any better ideas or suggestions on how to break the tie, or if anyone thinks that this is particularly unfair, please post here or forever hold your peace!
