What’s the evidence for these “sharp-valued classical observations” being real things?
Err...physicists can make them in the laboratory. Or were you asking whether they are fundamental constituents of reality?
I’m asking how physicists in the laboratory know that their observation are sharp-valued and classical?
Same way you know anything. “Sharp valued” and “classical” have meanings, which cash out in expected experience.
