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.
