That's one valid way to control error, yes. But I still don't think 
that's how the human brain achieves precision, for the most part.

Yes.

Really?

Or how about this: Try pressing the same keys on a keyboard in the same 
complex sequence, with your eyes closed.

Oh, wait... I can actually do that. And I frequently do. On a daily 
basis, in fact. Obviously my brain lacks the "precision" necessary to 
position my fingers to exactly align with the notes even though there's 
no tactile feedback until I actually touch the key...
