As regards medal tables, I assign 3 points for gold. 2 for silver and 1 for bronze. That way we derive

1 USA
2 China
3 France
4 UK
5 Australia
6 Japan

Next let's knock off 10 points for home advantage for France, moves UK up to third.

Then let's express the top 3 in terms of points per capita of population, and "we win"!!
