Uses calls a lot to move hands along. Stands out for being tenpai at draws, a high win rate and riichi-ing as soon as tenpai. Career record: +2.9pt per game, but allowing for luck the difference from average is not clear yet.

Net efficiency and morecalculated as on Mahjong Soul Paifuya, per hand
Net efficiency80874
Deal-in loss37648
Average win turn4112.38
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.

Columns about this player
Is Sonoda Ken really unlucky? (Japanese)Sonoda Ken, "the man who never hits ura 3". His career luck is about average, 19th in the league, while zero ura-dora with three indicators was a 1-in-240 event for him. The records show where the unlucky image came from.
Players with a similar styleclosest career style metrics first
This player's style differs substantially from everyone else's. These players are the closest matches.
Nobuhiro IshibashiFormer M.League playerIn common: Call-heavy, Immediate riichi often, Often tenpai at exhaustive draws
Yu SuzukiU-NEXT PiratesIn common: Pushes hard, Call-heavy, High win rate
* 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 supported more strongly by the data receive more weight. The comparison shows how similar the players' styles are, not which is better. Differences are often small, so the order may change.
