Next time, I’ll just write a bunch of nonsense in the rules and let you sort it out. :)
So:

1) In the first stage, if a mirror match occurs, you need to restart, not play a second random game. That is, mirror matches are prohibited in the first stage!

Mirror matches are played if the players want, but only if both agree.

Why not hold the final to five wins? It would be more logical, and then you could combine the 1st stage and the 2nd stage, and the 1-2-...-2-1 scheme?

Hmm... in the final, it is generally unknown how many games will be played. We can, of course, add another first draft, but there were already enough of them in the other stages... although we can assign it to the first two. Let's think about it. :)
But there should still be 4 games.

4th place in the second group isn't such a loser

We don't have any losers. :)

1-5 2-6 3-7 4-8

Indeed, it will be better.

No brains, you can't reach the top just on luck

I made it to the playoffs, I think :smile36:
