Ooi Takaharu

Riichis fairly rarely. Stands out for few deal-ins, being noten at draws and early riichi. Career record: +2.5pt per game, but allowing for luck the difference from average is not clear yet.

  • Deal-in rate after calling11.6%

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 efficiency885
  • Deal-in loss592
  • Average win turn12.29

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.
