Since the judges use the PCS scores as place-holders and to hold skaters up, they may as well go back to 6.0 for the second mark. I seriously doubt that the judges are parsing out all of the elements of PCS now anyway. They are just figuring that someone like Rachael Flatt should be somewhere in the 6's, while Yu Na should be in the 8's. In fact, now that I think of it, they should just make the overall PCS score the decimal in a 6.0 score. 5.85 for Yu Na, 5.75 for someone like Alissa (though she probably deserves more) and 5.6 for Rachael.
