WSOP KO records kept?

[Daliman]

Are any records kept as to who has knocked the most people out in one WSOP main event. Seems like CM killed off a lot of people, especially at the final table, and I'm wondering if he may have another record.

I wouldn't be terribly surprised if he was near the top of the single year KO list just becasue last years WSOP was the biggest yet by far. Of course I have no clue if such a list exists or not.
