To test the bot I'm working on, I've been having it go through the F1 league. Since it was taking forever to do 5 matches with each bot, I restarted the program and changed it to only do 3 rounds.
In the first contest, it won all three rounds - but the program proclaimed that a "Statistical Draw" and began a fourth round. And after that one was won too, it began a fifth.
(After the fifth round was also a win, it decided it wasn't a draw anymore)
Also, if there's ever a statistical draw requiring an extra round, every contest after that has the increased number of rounds too (This happens even when the number of rounds was originally 5, so you could get stuck at 6+ rounds per contest until you eventually lose a contest, for example).
Here's a screenshot from the Contest Results dialog after the third round:
