  "standard": "Derived from the standard definition of speed, in which the word PARIS is 50 dot units and one word per minute means one dot unit equals 1200 milliseconds.",
  "notes": "Values are computed, not transcribed: dot = 1200/wpm ms, dash = 3 dots, character gap = 3 dots, word gap = 7 dots. Farnsworth timing, which stretches only the gaps, is not represented here.",
