Say, P/T and V/T skate the skate of their lives. S/S mess up, K/S skate clean. K/S would be in 4th. Just like in Euro 2011, where their clean skate couldn't beat S/S's messy skate where the girl S was just standing around picking her nose for the entire spin.
If all skate clean, they aren't going to be anywhere near the podium.
Had they delivered in 2010, their PCS would not suffer so much.
