This is just bullshit. I don't know how they calculated this...

If you have a problem with the numbers, why not go to Wikipedia and dispute them / change them there? I haven't seen you present ANY valid counter sources other than your own ideas. They have a pretty good explanation with links to their sources. Wikipedia is one of the most widely used recourses on the net (although it is not infallible). If you feel so strongly about it, I imagine it would be more worth your time and impact a lot more people to place your efforts there. The problem is, you will HAVE to present your counter sources in order for your changes to be accepted.
