new theory.
australia usually does well because it is good at swimming and swimming is heavily weighted with medals. but this time, they have had a tough time in the pool.
the us team also does very well in swimming. this time the swimmers have been incredible. all the same, but for its dominance in the pool which has resulted in 17 gold medals, the us would be having a bleak olympics, well behind britain and northern ireland and about equal with south korea. that is on an absolute basis. much, much worse on a per capita measure.
in the absence of aussie dominance of the per capita chart, gb is currently leading amongst the 60 largest countries.
