And yet implementors reading the specification (the one with radius) HAVE cone up with very different results, that apparently went undetected for years, as there was no obvious way to know if the function was producing correct results or not. 

And in the end, once implementors are done implementing this, they can put it out if their head, largely. Whereas authors will collectively be writing it hundreds or thousands of times a day. It should make sense to non-mathematician authors, not just implementors reading the spec to know what functions to call.
