Consider the letter "E": a single "dit" in Morse, but it becomes
one "tap" followed by 5 "taps" in the above scheme. None too efficient,
it seems to me.

OTOH, the tap code is infinitely more efficient for sending T, M, O, etc.

Incidentally, didn't 'HI HI' originate from the way 'HA HA' sounds in
telegraph code?
