Of course.  But draws happen, and they get distributed over most of the players,
so they don't hurt too much.  If you have 32 players and play 5 rounds, draws
mean "clear first" might rely on tie-breaks...

But clearly 50 players would be better served by playing 10 rounds vs 10
different opponents, rather than five pairs of games against only 5 total
opponents..
