If the research was done properly it would remove small percentile anomalies, that means that there is enough 200lb+ women to ballance all of the people 30lb less than average.  It's why everytime I see a slim(er) person I can't help but think there is a doubly fat person somewhere to make up the average weight. That and it doesn't help that the average weight is now pushing obeast territory when you do a quick bmi calculation.  How this is not an accepted health epidemic is mind boggling
