(Actually, a good test for whether someone has A-lister perception is to see if they can see past their own prejudices.)
Because, in your words, someone should know on the face of it, that "seven proxies" is implausible? Please explain how I should know that. Would it be worse or better if it were 6 or 8?

(The fact that you are not accounting for the fact that there are multiple interpretations to the term "proxy" makes my eyebrows raise.)
