No, but with thousands of different colleges in the U.S., it’s not out of the realm of possibility. I do take exception with the idea that “while your fafsa may imply 0 EFC, each school has its own calculation.” As far as I know, schools that use FAFSA only to determine need-based aid (and that means most schools) do not calculate a separate EFC; they use the EFC that FAFSA has calculated for them.
