99%In my (software) industry it is dismayingly common to think you are 99% done on a project only to find a game of whack-a-mole ensues that can reduce that number to 80, 60, 40, 20, 0, depending on the project (this is endemic in the industry because of the hopeless flexibility of software).
I am not sure lying can be so tricky.
Though Edwards implies that he was being "99% honest" when he was lying, and that "I used the fact that the story contained many falsities to deny it," he didn't just deny that the story was true. He said it was "completely false."
(Disclaimer: I know people who know Edwards, and they really like him, as a person.)
