Pairing according to elo in tournaments

The way you describe them, it sounds to me more like you're referring to club matches, where the strongest members face each other, until the pairings are completed with the lowest-ranked players.
Because it sounds strange to me that it's in daily tournaments, where the highest-ranked players are paired with the lowest-ranked players practically every time, every round in his KO or multiple players group.
Or maybe you aren't referring to correspondence chess... on that phrase "daily tournaments."
