O’Sensei was giving a demonstration for the purpose of having photos taken for a newspaper article.  The photographer missed a shot that he thought would have been excellent and asked O’Sensie to do the technique again. After O’Sensie had done it a couple of more times the reporter asked him to do it the way he had done it originally and O’Sensie explained to him that  he couldn’t because each attack is different and the technique changes to fit the  way that it unfolds and therefore you can’t simply repeat the same movement/waza over and over in a randori situation but rather the  waza  has to fit the  individual attack.
