what was the real number according to USSR?
The Mexican comedian in my last link, although in a humorous context, actually provided that information, or, at least he provided the new figures per camp (now claimed by the various museum authorities), adjusted after the release of information from the former Soviet Union in the early 1990s.
Personally, I'll go with the numbers released by the International Red Cross shortly after the war, as they had the fewest dogs in the fight one way or the other, and were merely attempting an accurate count, having themselves been present in the camps on a regular basis during their operation.
