I imagine the veterans and experts "Zcodes" should have realized this.
That the number of letters (discarding symbols) added the Z408 and Z340 is = 341. (Which is quite near to 340)
The symbols for logic, are 407 (which is right next to 408)
I was thinking of 3, 14 number , a PI
Finally, another digression and my mental game.

Hello. 
Whenever working on my new theories (z 289), I review my old to see if there are any clues.
I made a recount nullifying all alphabetic the Z408 and Z340 symbols using webtoy in the site of Mr Doranchak .
To my surprise … 
There are a total of 408 non-alphabetic symbols and 340 alphabetic symbols 
I believe it is not coincidence. There must be some meaning to it.
symbos in Z 340 / Z 408
Z 340 = 142 ALPHA 198 not Alpha
z 408 = 198 ALPHA 210 not Alpha
See image below.

Hi 
The only discrepancy is the letter I,
In the Z408 is written this way
and Z340 is written in this way
but,within the standard used in any language i think.

Hi
I wondered, why use two different modes for letter I in the two ciphers.(408/340)
"In the Phoenician alphabet, the letter may have originated in a hieroglyph for an arm that represented a voiced pharyngeal fricative"
https://en.wikipedia.org/wiki/I
I noticed that the letter I in Phoenician is similar, in part, with one of the symbols of Z.
As the source, which would be derived from the word arm, still do not see correlation.
ARM =Armed Forces ??!

Just a digression to the symbols alphabetic letter I.
Can refer to first person singular nominative case personal pronoun??!!
And adding something more nonsense, could refer to two Selves, two person or double personality ?? !!

Hi
I was alerted by a member face (Mary Olson), something that was not seen, was not given the letter Q as alphabetical, perhaps to be blurred or unclear, always mairia of times londo the cipher, written as if the trace crossed the symbol.
That is there is an error, and the correct would ratio
203 (alpha) 205 (not alpha)
result in which all cipher (408/340)
in 403/345.
What is next, but it’s my mistake.
Sorry.

Hi ,
i look in the http://zodiackillerciphers.com/wiki/index.php?title=Encyclopedia_of_observations#408_and_340
The letters Q an C They can be the "keys" connection between the two ciphers.
the five to 408 0r 340
Z408
198 ALPHA
2O5 NOT ALPHA
5 LETTER Q
Z340
137 ALPHA
198 NOT ALPHA
5 LETTER C
RATIO 408/340
ALPHA SYMBOLS (EXCLUDE Q and C)
335
NOT ALPHA SYMBOLS
403
Q = 5 SYMBOLS
C = 5 SYMBOLS

Hello.
Maybe, the letters C and Q, are words with phonetic value next to SEE KILL
