I myself played a superfinal under the current system in some m200 tournament, and being in the winners' bracket, we just played until someone reached 2 wins. I won the first game, then lost the next two. Considering that I had already beaten this same player earlier in the tournament in the winners' bracket (sending him to the lower bracket), it felt quite strange. But since that was the regulation, I didn't object.
