For example, if a match between Stinger and UnknownPlayer doesn't take place for some unclear reason, there's a high probability that Stinger will be declared the winner.
And if the match between UnknownPlayer1 and UnknownPlayer2 is delayed, there's a strong desire to award both players with zero points.
This is based on observations of the judges' behavior in various tournaments on different platforms. And it's not just in Heroes; it's the same in other games.

I'll comment on this part as well.
With this result (0 wins, 0 draws, 1 loss), you shouldn't qualify for the playoffs under ANY rules, and it's good if you understand that.
In general, if there is very low activity in a particular group, it makes sense not to determine the playoff participants based on technical criteria, but to take them from another, more active group. I would probably do that...
