My proposal was essentially different:
a round – players play the same map: A1 (red) – B1 (blue), A2 (blue) – B2 (red).
Thus, the same map is played by a team for both colors. In case of a tie in points, a time rating is used (score options: 2-0, 0-2, 1-2 (team B wins based on time rating), 2-1 (team A wins based on time rating)).
