So you achieve freedom from buzz at the expense of accurate intonation? .5mm ( = .020") is huge, and unless the nut is compensated, I would think the pitch at the first fret is guaranteed to be sharp. If the open strings are buzzing, then surely the relief need to be greater, or else the saddle needs raising?
Admittedly, my experience is only with steel strings, which is why I would like the opinion of a bona fide classical luthier.
