The same could happen in groups C, E, G, H, and J by the end of the stage.
Then we'll all be waiting for a month to see how the round-robin ends? And then toss coins?

I meant specifically this group, because they still have time for both a round-robin and cross-group matches.

On the other hand, of course, we are not going to interfere with the gameplay. If you want, play. Whether to count it or not, we will decide when summarizing the results of the groups.

What reasons could there be not to count it if the players agree? "Consent is a product of non-resistance" C
If the guys agree and quickly play a round-robin, then there is nothing wrong with that.

In my opinion, linking such a serious tournament to the seasonal ranking makes sense only if there are no other objective ways to identify the strongest player.
