As usual, I'm late the party and you've already kind of made up your mind, according to your latest post, but for the record< I agree with everyone else who said you should go for the job. Everyone make mistakes and while I can understand why you think that yours might preclude you from consideration, but I don't think you should let that deter you. It might well not even be a consideration since it has happened and been dealt with already. You don't know until you try. Based on what you have said here, it sounds like you are qualified, so why not go for it?
