^ From my understanding after watching most of the audition episodes, he reviewed tapes (DVDs?) of performances from the auditions. I guess this came in handy when he chose to bring back the girls that had gotten kicked off the show, and when he decided that two of them (Anchii and ReiRei) would be in the final group, after they went to the "last camp" thing.
But he wasn't physically there in at the Auditions until the final episode, when he chose from the still remaining girls, who would be in the group. Then he brought out Anchii and ReiRei after choosing the first 4.
So he wasn't really a judge, he was never there for the episodes to score in on who he wanted to stay, who he wanted to leave, etc. - they had different Taiwan/Chinese celebrities that did that job during each week. But Tsunku had "ultimate" (
) power above the judges choices, as shown with our Anchii and ReiRei.
