ReallyAnnoyed,
Using phrases like, "I believe", "probably", "most likely" and "I think" you have come up with retarded figures and then actually taken the time to put those retarded figures into a database. You then produced a take-home figure right out of your ass which other posters are now asking your opinion on.
Why are you posting numbers when you have absolutely no idea?
