Worth knowing before you trust the numbers: the scorer put the cook's actual opening hook — "Check it out, folks. If you like a chopped cheese, you're gonna love this" — last, at 68, and ranked a mid-video aside about breaking up the meat highest, at 82. The score measures hook-like structure inside the window you hand it. It is not a prediction of views, and we don't publish one, because we haven't measured one.
