Ah! The confusion was mine. Both ways. a) Here is accuracy
  Accuracy is not precision. == Metaphors connect two concepts
  from often vastly different "fields" and draw them together. A
  metaph[1]precision_accuracyor is a fancy analogy. It's an
  analogy. Drawing comparisons. So, metaphorical accuracy means
  both: The metaphor is accurate and also the accuracy is not
  necessarily accuracy per se but bears a metaphorical resemblance
  to accuracy. In short: the metaphor is metaphorically accurate.
  The accuracy is metaphorical. That might not have clarified it
  for you but I'll await further instructions.
