Uses calls a lot to move hands along. Stands out for riichi-ing as soon as tenpai. Career record: -6.5pt per game, but allowing for luck the difference from average is not clear yet.

Riichi and callsbalance and outcome of hands with riichi or calls
Income is the average points won or lost in those hands (riichi sticks and honba included).
Net efficiency and morecalculated as on Mahjong Soul Paifuya, per hand
Deal-in loss = deal-in rate × average deal-in; net efficiency = win rate × average win − deal-in loss. Win and deal-in values include honba and riichi sticks. Win turn is the number of tiles discarded at the table when the win came ÷ 4 + 1. Win efficiency (win rate × average win) is not shown: players with a high win rate win smaller hands, the two cancel out, and differences between players cannot be told apart from chance.

* Twelve style metrics, including call rate, riichi rate, win rate, deal-in rate, hand value, riichi speed and immediate riichi rate, are put on the same scale and compared; the players closest overall are listed. Metrics supported more strongly by the data receive more weight. The comparison shows how similar the players' styles are, not which is better. Differences are often small, so the order may change.
