It does not mandate
that the relative spacing meet any particular standard to be considered
Morse code.

So you say that Morse cannot be defined, yet the FCC demands you pass
an exam that has barred people from the medium and high frequencies.
It is whatever you want it to be.

Morse code is very clearly defined. Each letter, number, etc has a defined
combination of dots and dashes. There is no ambiguity whatsoever. For
normal conversational speeds (13wpm to 20wpm), the standard spacing allows
one to develop a natural, easy rhythm. For low speed operation (less than
13wpm), it is better to have the letter speed be at least 13 but spaces
between the letters. It's actually much easier to copy that way as you hear
the letter as a distinct sound rather than counting dashes and dots. On the
other hand, high speed ops may choose to change the ratio of the length of
dashes to dots as it may be clearer than the "standard" spacing.
