Nickname for Wakanosato coined by Mike and Kenji. Wakanosato measures the performance of the other sanyaku rikishi each basho. If a rikishi loses to Wakanosato, he is not performing well enough to yusho. This formula held true from the time Wakanosato entered the Makuuchi division until the 2003 Haru basho when Wakanosato beat Chiyotaikai, who later took the yusho at 12-3.
