World Championship in Heroes of Might and Magic III.

Are you delusional? This is a standard "double elimination" system; the grand final is always played with an advantage for the winner because they haven't lost.

Where does all this unfounded self-confidence come from? I've participated in double-elimination tournaments many times, and I've never seen such NONSENSE with a different number of wins. Such an advantage is given ONLY when a pro plays against a beginner. For example, sometimes a Candidate Master (KM) might give an advantage to an amateur.
