The Ohlencamp site supports the Nishioka position and further elaborates on the Nishioka paper further stating:

"The Japanese word sensei literally means "one who has go one before". This is another way to look at the role of a sensei, and one that I especially identify with. In terms of a martial art, a sensei is the one with more experience who can guide you along the path. My sensei competed extensively and knew what it was like to win and lose. Having demonstrated the required techniques to go through each of the ranks he was competent to help others along the same path. Having studied other martial arts he had an appreciation for the unique lessons of Judo. Being head coach of a large Judo club he saw a lot of students struggling to achieve their best. Having coached winning athletes he knew what it took to be successful. Sharing this knowledge and experience with others is what a sensei is all about. Ken Shiki, or "the pursuit of knowledge," is an important virtue of judo practice and it is based on the foundation of the sensei's experience."
