Too little data yet to pin down the style. Career record: +45.7pt per game, but allowing for luck the difference from average is not clear yet.

Colour only for metrics with a good side (red = good, blue = bad). Metrics of style, such as riichi rate, call rate and efficiency match rate, are grey. For tenpai turn, further right means later (a larger turn number). Values are estimates.

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.
