Both sides are set at the same size on purpose. Kill The Body does not score a second-round knockout above a split decision — the edge counts losses first and wins as the tiebreak, and the rest is yours to argue. Shared opponents are matched on fighter identity, not on name, so two different fighters with the same name never merge into one row.
