Huh, my guess is the opposite. That is, all expert plumbers are similarly competent at performing tasks, and the thing that separate a bright plumber from a dull plumber is how quickly they become expert.
I don’t know much about plumbing, but a possible explanation here is that there’s a low skill ceiling in plumbing. If we were talking about chess, or Go, or other tasks with high skill ceilings, it definitely seems incorrect that the brightest players won’t be much better than the dullest players.
