I think, if you give any answer to a question and later the question has been closed due to some reasons then it might considered in the account page.
so may be it applies the same logic on answers too.
If it is the correct reasoning then still it should be correct.
You've answered this question two times.
may be 102 answers in your profile mean that you have answered 102 questions.
but account page is probably actally counting your answers, so it is total 103 answers.
ps: I don't mean this shoundn't fix, but I noticed like that.
