Germany -  four entries 

You did not respond to my argument at all - please read it more carefully:

The IOC cannot be seen as the single authoritative source on this article, as the IOC itself does not publish all-time tables, and publishes only unofficial tables per single Games. Therefore this article is in violation with WP:No original research! The official source for the German National Olympic Committee (DOSB) does list the Olympic Medals for Germany from 1896 to 2012 → .

There were no official country codes before 1976: Only in 1976 did the IOC start to assign standardized codes. Before that time, the local Organizing Committees of each Olympic Games had chosen codes, often in the local language, resulting in a multitude of codes.

At the Games of 1956, 1960, and 1964 the German team was simply known as "Germany" and the usual country code of (GER) was used. Yet, the IOC code EUA is currently applied in hindsight in the IOC medal database, without further explanation given. 

Yugoslavia does not exist anymore as a country - the FRG does. The (FRG) Federal Republic of Germany did not cease to exist. It was a simple code change, same country, same NOC. NO alternate NOCs: EUA, FRG and GER have always had the same German National Olympic Committee (NOC) recognized in 1895, same NOC President (Willi Daume, 1960–1993), same Olympic Committee located in Frankfurt - only the codes have changed. Germany is officially still called (FRG), the Federal Republic of Germany - it's the same country, with the same NOC since the first modern Games held in 1896 - only the GDR had a separate NOC, because it was a separate country (although not recognized by Germany). "West Germany" did never exist, and is nothing more than the common English name used for the Federal Republic of Germany or FRG. The "enlarged" Federal Republic of Germany (known simply as "Germany") is thus the continuation of the pre-1990 Federal Republic of Germany - the very same country, with the same National Olympic Committee since 1895.
