By the way, it's been a while since we had a paired tournament. Perhaps the problem lies in the templates, but I think it's solvable; the main thing is to start.
1) Getting everyone together at the same time (4 people) is problematic.
2) You get together, and someone suddenly has to leave - game over;
3) You get together, and someone's internet starts glitching - you get nervous, game over;
4) You get together, and there's a disconnect, you don't know who, you get nervous, game over;
5) You get together, start playing - the turn limit is 10 minutes, turn-based - the interval between turns can be over 30 minutes, and then the player whose turn it is has to leave - you play, sit, and wait;
6) An error (loss) for one, a problem for another - nervousness, complaints (possibly), and so on.
Personally, what bothers me most from this list is waiting for my next turn for more than half an hour, and that's if everything else goes well:)
