After two years of testing and the promotion of a new system by International Skating Union (ISU) president Ottavio Cinquanta, the IJS was adopted at the ISU Congress in 2004. The last time the 6.0 system was used in the U.S. was at Nationals in 2005, which Lynn Zinser of "The New York Times" called "an ode to the 6.0" because the judges awarded the competitors so many 6.0s. British ice dancers Jayne Torvill and Christopher Dean, who earned the most overall 6.0s with 56, earned 19 perfect 6.0s at the 1984 Olympic Winter Games and 29 at the 1984 World Championships. Midori Ido from Japan has the most 6.0s in single skating, with 10. Irina Rodina from Russia has the most 6.0s in pair skating, with nine with two different partners.
