Wow! No wonder there is rank inflation in Japan. It used to be that to make shodan you had to win 4/4. (I also think that you could make shodan with 3/4 wins in consecutive tournaments.) And you could not try for *any* higher dan rank without a diploma for the next lower rank.
"Win at least 2 out of 4 games against players applying for the same dan rank." (emphasis mine)
Rather telling...
