You're missing my point -- I was objecting to the "(at least among the innumerate)" bit. It would hurt YC's reputation among everybody who matters, whether innumerate or not, if 70% of YC companies didn't survive past Demo Day.
Maybe this is just idiomatic, but when I see "it is thought (at least by people with property foo) that...", I read the parenthetical comment as meaning "people without property foo don't think this way".
