To take a graph we know both quite well, it's just impossible that the full id.loc.gov contained so few as 27,392 SKOS triples. Or have they captured a state in which id.loc.gov did *not* contain LCSH?

I also have the sense that these big general crawls can be a bit lumpy/quirky. However they can give ud starting points for recrawling more specific targets more comprehensively.
