Fujisaki Satoshi

In style, stands out for caution in not riichi-ing at once and keeping shape and value over ukeire. Career record: -6.6pt per game, but allowing for luck the difference from average is not clear yet.

  • Deal-in rate after calling13.8%

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

  • Net efficiency797
  • Deal-in loss644
  • Average win turn12.39

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 the data can vouch for weigh more. It shows only how close the styles are, not which is better. The differences are often slight, and the order could change.
