Yes, I needed to clarify this within the spec -- that it's just a matter of
typing speed.

A very fast typist (and/or a longer interval) would result in fewer stanzas
similiar to one stanza in Section 7.2 because they would have typed the
whole thing within one interval cycle.   While a slower typist (and/or a
shorter interval) typing exactly the same message with the same errors,
would result in more stanzas similiar to four stanzas in Section 7.3.

Basically assuming a default transmission interval of 700 milliseconds...
...This would mean section 7.2 would occur if the typist was able to
type/correct/retype the whole thing in 700 milliseconds.
(That would require unusually fast typing, like court-reporter stenotype
speed or voice-recognition speed)
...and section 7.3 would occur if the same thing was typed over four
transmission inteval cycles (700 x 4 = 2.8 seconds), more akin to normal
typing speed.

So, it's just a matter of adding a sentence or two that explains the
interaction between transmission interval, typing speed, and resulting
number of stanzas, that's all?  And/or rewriting the examples to cover more
realistic typing-speed situations (i.e. 8 keystrokes in 1 stanza, versus 4
stanzas of 2 keystrokes each)
