So this should read What's you are all time winning percentage? That's what I thought the contraction you're stood for. Your means belonging to someone or something.
I wasn't on here correcting someone else. I would never do that because I read and type to fast and dont really give a crap about proof-reading. I graduated HS, got a really good job with Mercedes (going into the Navy soon)...Who gives a damn if I spell something wrong or use bad grammar!?
