Standard Morse timing is built on one unit (the “dit”), and everything else is a fixed multiple of it:
Dot 1 unit
Dash 3 units
Gap between dots/dashes within a letter 1 unit
Gap between letters 3 units
Gap between words 7 units
DayZ values break this in a few ways:
Dash is 3x the dot, which is correct (0.5 → 1.5).
Symbol gap (0.4) is shorter than the dot (0.5). It should equal the dot length. This is probably fine.
Word gap (2.2) is only about 4.4 units. It should be 7 units, so words don’t stand out clearly.
There’s no letter gap setting (WTF?)
Especially the wrong word gap makes it hard to decipher, also the symbol gap is confusing.
Two practical notes for a game:
Beginners often find it easier with a longer letter gap. This is the idea behind Farnsworth timing: keep the dots and dashes at normal speed but stretch the gaps between letters and words. Try a letter gap of about 2.0 and a word gap of about 4.5 if 1.5 and 3.5 still feel cramped.
0.5 s per dot is slow (about 2.4 words per minute). That’s fine for a game where players need to decode by ear, but if you want it faster, scale everything by the same factor, for example a unit of 0.25 s with a dash of 0.75, a letter gap of 0.75, and a word gap of 1.75.
And faster would actually be easier to read (imho), with a longer letter/word gap - so you can count the dots/dashes and then have time to write them down.
