Riichis fairly rarely. Stands out for a lowish win rate, late riichi and being tenpai at draws. Career record: -1.6pt per game, but allowing for luck the difference from average is not clear yet.

Net efficiency and morecalculated as on Mahjong Soul Paifuya, per hand
Net efficiency18798
Deal-in loss71624
Average win turn312.53
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.
