World Karate Federation (WKF) is working hard to get Sports Karate into Olympic Games.
There is a serious problem with quality of judging of Karate Kumite (Sparring) tournaments: Unclear Rules of competition.
Rules can be found here http://www.wkf.net/pdf/wkf-competition-rules-version9-2015-en.pdf. Despite pages and pages of instruction, there is fair amount of subjectivity. The phrases like, “Zanshin is that criterion most often missed when a score is assessed” do not help in lending the objectivity.
