It would be good to see a statistic in the end by Continents. I have always had a thought that the time zones and weather patterns could be having a slight edge for countries surrounding the host region. It could have no relation of course, but Europe usually does worse by my account when the games are on other continents and vise-versa. Like i would be shocked, if Asia and Australia (Oceania) have the same successful Games in Paris, like they do now.
