What are the conditions for matching World War opponents?

[Arknights P R T S]

We've agreed on a matching time through communication with the top guilds, and started World War matching 8 hours ago, but we still haven't met anyone.

This wasn't the only time this happened; it's happened countless times before. Sometimes, matches took 14 hours to complete. And sometimes, matches were made in just one minute. I wondered what conditions were in place for this seemingly inconsistent system.

Feel free to review the conversation here that covers this very subject.

Just one confirmation: to compute the alliances war weight, are ALL members included or only the ones that are part of the war roaster?
I ask because we have some high level members who not participate in wars. So if their weight is included in the matchmaking, I will not keep them in the alliance. Or they need to play with us in world wars.

One knows?

It makes me doubt due to this sentence of Harlem: Step 2: We do some math. We combine all of the war weights of each player in the alliance into a total "alliance war weight" We don't do a simple summation here because we don't want to heavily disincentivize alliances from bringing along a couple weaker players to show them the ropes.
