On paper, as a mathematical abstraction, sure.

But that's not at all what we're talking about. We're talkin about
people actually ringing, making noises spaced out in time. Except
perhaps in reruns of Star Trek time does not wrap around and start
again. And the rounds at the beginning of peal is often at a different
speed than that at the end; they're hardly the same thing. And you're
more tired and your hands potentially hurt more
