it says 'you may encounter...'

anyways, it works in a simple way: whoever is in queue before gets the priority.

why were you matched with a player with a comparable level to yours?

because he was in queue before you AND or he lost his previous match or he was waiting since more than 60 seconds or he was at his 1st match.

In these 3 situations you are matched with him because he was in queue before you.

It's stu[pid, i know, but is how it works.
