NOTES
*1961-1976 World Championship and 1972 Olympic matches that feature countries that use full time athletes and those that don't playing each other will not be counted
*1961-present World Championship and 1976-1994 Olympic matches featuring Canada and United States are not counted due to these countries sending poor representation
*1976-1986 Olympic, Thayer Tutt Trophy, and Asian Games matches featuring countries that do not use full time athletes will not be counted

COMMENTARY
*due to the regimental structure of scheduling by the governing body of the sport there will be inaccuracies (usually small, in some cases large) in ratings from year to year based on divisional results, however, they will normally fix themselves by the following year
