It isn't a question of "if" or "I suggest", it's fact as proven by the citations above. I changed them because "head of" is informal, and inconsistent as some characters, such as Jeff Russell, have never been referred to on the show as "head of", while others have been interchanged between "head of" or "chief of". Also, given that the documentary showed Mark and Derek with their "chief of" titles, it removes the inconsistency of how a character is formally/informally referred.

And yes, you are correct, the documentary episode was in season 7, as my earlier response was a typo. My apologies.

However, the information is still correct.
