While that seems reasonable, it assumes the amount of impact per paper has remained constant, while is practice it has greatly declined. These days scientists will literally try to identify the set of "least publishable units" in a research project to maximize the number of papers (I've attended meetings where this is discussed without irony). There is also a tendency to publish work that is quite similar to previous work with a minor change that is emphasized disproportionately to its importance.
