Maybe they need to consider the idea of better-than-random pairings. What this means would be a subject for discussion, but for example there could be heuristics that say something like pairings need to at least look random. What does that mean? Again, it's a matter for discussion, but just to take the Yifan situation as the example, seven out of nine paired with the same gender does not look random. Just saying "it's decided by machines" is not sufficient. They have to say what the rules are that the machines are going by, and what is the source of randomness exactly. And then they have to address the point that maybe pure randomness is not good enough.
