I work on a video game that's approaching 20 years old. I don't think in our case that this distribution would hold, because for instance if you took our top engine programmer, he probably wouldn't know off-hand how to work with our texture pipeline. Nor our web store. Nor our customer support tools. He'd probably be capable of figuring any of them out, but in terms of "knowledge at rest", I doubt anyone knows even a third of everything there is to know, even if we constrain ourselves only to knowledge of things within the engineering discipline.
