A bit of advice for future research (and this is not meant to be offensive, just good life lessons): Learn what a reputable source is, and remember that anyone can put something up on the internet, and can even make it look very professional. You will probably never cite from a forum. Follow the information. If what the person is saying has any merit, they will probably also have cited information, this guy did post a link to another page (probably only his own website though) but that link was broken.
You said later that you didn't believe the number was correct, why not just cite the forum and ask outright if this was right or not? You would have gotten your answer quicker and easier.
There are a lot of guys on here who know what they are talking about, and don't ever think you can trick them by saying something that is not true, you will be eaten alive. Just a fair warning.
