Katarina and Claudia Leistner were very much the international "It Girls" that season. (Alas, Leistner went downhill, for a while, after 83 Worlds.)
Witt was the Euro Champ. So her time had definitely come. The win in Sarajevo was not at all a surprise to those who live in those times and attended major events, as I did. Roz was a pretty and pleasant fluke.
The "surprise" was that Witt went past 1984. Nobody in the 1982-84 period would have predicted the longevity of Witt in amateur competition.
