STYLE PROFILE   7 chunks, 4,496 words

As a reference   held-out Delta 0.68 typically, 95% under 0.89 (7 documents)
  Shorter texts: calibrated at 75 words (124 pieces), 150 words (56 pieces); not at 300 words (28 pieces from 7
  documents, worth 18 independent ones), as a length needs 20 independent pieces from 3 or more documents. Under 75
  words, no verdict.

Pass --all, or run `styleprofile show` on it, to see the metrics.
