This study deals with "Street Fighter League", which is official team league matches using the fighting game "Street Fighter series" released by CAPCOM. Machida and Adachi (FIT2023) evaluated players by the number of wins and losses per battle. Machida’s result is different from the official ranking. Under the rules of this tournament, it is conceivable that a player could strategically and intentionally lose one battle to win a match. We introduce the ratio of points gained and lost, such as K/D ratio in games such as FPS. In our schemes, among the 32 players, three of them changed their ranking by more than 10 compared to the official ranking, and one compared to the Machida’s scheme. We can find four strong players. Furthermore, the proposed method can be applied in the future when the number of participating players and e-sports tournaments increase, and different tournaments can be compared.
