The WRL placement modifier is based on the placing difference between the two teams on the latest World Ranking List before the tournament. This means that if team A is far above team B in the WRL, team B has a higher multiplier and viceversa it will be smaller for team A. The closer two teams are on the World Ranking List used as base the closer the multiplier will be to each other. The modifier is always at least 0.1, it cannot be less than that.
