Doriki

Fukurou's te-awase (手合わせ, "contest") ability allows him to measure the Douriki (道力, approximately meaning "power level") of his fellow teammates. The Douriki is basically the physical power of someone, and as such has a proportion with the Rokushiki skill. A common armed soldier on average has around 10 Douriki, and according to Spandam a Douriki of 500 or higher is easily superhuman.

According to Jyabura, Douriki only measures someone's physical power and doesn't take in count Devil Fruits. Despite that some Devil Fruits' (especially Zoan-type) side-effects directly increases someone's physical strength, no more detail were given on how Douriki would result with it.

It seems that Rob Lucci, Kaku and Jyabura are the top three members of CP9, as their Douriki are all drastically higher than the others. It also seem that early Jyabura had the highest Douriki of all of CP9; he also commented that had never heard of a number as high as 4,000 before Rob Lucci. Nero's Douriki is never given, but due to Lucci declaring him not to be superhuman for knowing only four Rokushiki techniques, it can be implied to be lower than 500.
