That makes sense.  8 cps is 80 wpm assuming 5 character average word
length (which is the English convention at least when talking about
Morse code).  80 wpm is a respectable rate but there are lots of good
typists that can do better.  The fastest I have ever seen is 134 wpm,
which is well beyond what an ASR33 can do, never mind those old 5-bit
machines.
