at least for me 
.. and for at least 2 reasons:
1. number of medals pro population (weighting gold > silver > bronze). Here the table
2. number of world records pro million of inhabitants (ok, I didn’t calculate it for each country, but I am pretty sure no country performed better then Jamaica: 3 world records and 2.8 Mil people - for comparison Australia: 7 WR and 21 Mil people)
One should also consider the kind of gold medals and world records Jamaica scored. (Athletics 100m+200m+4*100m, which are among the top competitive discipline at the olympic games)
Ok, Athletics is only a part of the Olympic Games, and I don’t want to say Athletics is more important than other sports, but how to say.. I am so happy for Jamaica!
