I'm with you on this one. The Olympics comes only every four years so and it's not fair or realistic to expect many skaters to go to more than one so that the OGM can be a career achievement. For some skaters, the Olympics comes around when they are only 16 but that may be their best chance to win gold. Who know what will happen four years later??
Oksana Baiul and Tara Lipinski had short competitive careers but when their Olympics came around they were considered favorites for the OGM and they need to go for it right then and there, regardless of their age or how many worlds they had gone too. (And for what it's worth Tara's "upset" is not remotely on the same plane as Sarah Hughes'. Tara was already a national and world champion and she was a very tough rival for Michelle Kwan. Her OGM was not out of the blue at all. True she looked like she was 12 and not 15 but that's a whole different thing )
