Actually, that's not true. A second (or third) in an uncontested heat is last place. A first is a first, though less significant than a contested first. I've seen second places in uncontested heats. And ... it's not the fault of the dancer that their heat(s) was/were uncontested. They've got no control over who else shows up in their age, division, etc. Not that I think bragging about uncontested firsts is really cool. (Bragging in general is not so cool, but anyway.) But they still went out and danced and earned that much. Which is more than you can say for whoever else didn't show up to compete against them. Let them enjoy it, it's not hurting anyone else.
