That's very nicely done.

The adjusting for population one is very funny though - I like the strategy of 'win one gold medal, have very few people' adopted by Grenada!

Yes, that is unfortunately the problem with per-head or per-dollar-GDP systems; they seem a fairer way in principle to judge merit irrespective of size, but when countries get down to the point where the expected rate of medal-winning is a fraction of a medal per Olympics they develop the problem that the interesting parts of the table are composed of noise rather than signal...

Though Jamaica has done rather well even not taking population into account :)
