Bebe Liang deserves a mention in this thread. I remember her finishing 5th at the 2005 Nationals, which I and many others found utterly ridiculous. The program difficulty, transitions, interpretation, and quality of elements was all better than that of Meissner and Kirk, yet she was placed behind them in the short and even got 5.0s. In the long, she landed more triples than Jenny but was still behind her.
The following years, she was consistently lowballed in PCS - I remember her consistently getting lower PCS than Czisny, Meissner, and Hughes, which is more a reflection of the USFSA's political preferences rather than actual PCS.
I'm also surprised that Maria Butyrskaya hasn't been mentioned yet, considering that she is so often discussed on FSU as a victim of bad judging
