Income is the average points won or lost in those hands (riichi sticks and honba included).

  • Average win turn12.37

* Hatched metrics have no league rank: too few games (10 in a season, 40 in a career). The values on the right are estimates pulled toward the league average as far as the data is thin.

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.
