He didnt "admit" anything...he said that it was close, and that he pulled it off by posing his ass off and getting the crowd into it during the evening show. Pearl let him know that he was in 3rd in pre-judge, so arnold turned it up at the finals, game over
How is that an admission? Besides - who else could have won? skinny Zane? chestless blocky Mentzer? They were all B class BBs as soon as arnold showed.
