As I understand, if there are 2 or more competitors, the top 2 placements MUST count.
If you think about it, it's fair -- otherwise, those who have more skaters in the current competition would have more chances to get those podium placements. Thus, it's fair that the placements of the top 2 in a 3-member team, or both if it's a 2-member team, must count.
Thanks for the clarification, rallycairn; much appreciated.
Exactly right! I'm so tired of conspiracy theories being the explanation for every disappointment of ice dance fans...
