The table looks a bit messy. I think it would be better to use a chess-like plan – a total score between teams. For example, 6:0, and on the other side, 0:6, and so on, or 5:1 - 1:5. Otherwise, it's hard to understand. In this format, EACH game will contribute to the overall result. As it is now, you win two games, and the third game essentially doesn't matter. This removes the incentive to play it. Here!
I'm leaving my computer for 4 days, and then I'll fix everything in the tables.
