Let me see if we can work together to solve this puzzle:
In Atlanta, 197 going + 0 not going = 197 nations
In Barcelona, 169 going + 0 not going = 169 nations
In Seoul, 159 going + 3 not going = 162 nations
In Los Angeles, 140 going + 13 not going = 153 nations
In Moscow, 80 going + 62 not going = 142 nations
In Montreal, 88 going + 26 not going = 114 nations
In Munich, 122 going
In Mexico, 112 going
Considering the fact that these numbers represent registered nations and the effect of conquests and independance, particularly of African nations in the late seventies, the numbers do not seem far fetched to me. They seem to fit the growth curve rather well. They agree within +/- 1 with those found in Encyclopedia Britannica and I tend to trust that source.
Encyclopedia Britannica Olympic page for 1976 & 1980
Another thing that might shed light on this matter are the international Olympic committees recognized in 1976-1980. These include14 committees from 1978-1980:
(data from the
International Olympic Organization)
Antigua & Barbuda 1976
Cayman Islands 1976
Gambia 1976
Cyprus 1978

Mozambique 1979
Lao's People Democratic Pepublic 1979
Mauritania 1979
People's Republic Of China 1979

Vietnam 1979
Angola 1980
Bangladesh 1980

There are still some unexplained discrepancies but I am not anal enough to go through the world history between 1972 and 1980 in detail to try and explain them. Maybe you should give it a try.

As for 1976, I seem to have typed 'which' in the wrong spot.
Consider...
-because of the presence of the New Zealand, which rugby team had just recently toured in South Africa.

I edited the booboo. LOL. I bet that kind of typogrammatical error could cause a war some day!
Keep up the good posts, Dabanshee. I always enjoy reading them and learning the odd detail.
