１．The pair who has a higher “acquired match rate” stands at higher rank.
［Acquired match rate］
＝［N. of all the acquired matches］／（［N. of all the acquired matches］＋［N. of all the lost matches］）

２．If the acquired match rate is same, the pair having a higher “acquired game rate” stands at higher rank.
［Acquired game rate］
＝［N. of all the acquired games］／（［N. of all the acquired games］＋［N. of all the lost games］）

３．If the acquired game rate is same, the pair having a higher “acquired point rate” stands at higher rank.
［Acquired point rate］
＝［N. of all the acquired points］／（［N. of all the acquired points］＋［N. of all the lost points］）

４．If the acquired point rate is same, their rank should be determined by the following method.
１）If 2 pairs stand at same point rate, the winner at their head-to-head match stands at higher rank.
２）If 3 pairs stand at same point rate, their rank should be determined by lottery or by organizer’s decision.
