Yeah, with syntax all over the map.
The parenthetical is also a convention used in algebra/math, and can have the same "times three" function.
It can also be used to designate a sub-part, rather than multiples.
I see two lines ... "USMC activated" then separately, "US (3)"
If we follow your convention strictly, which is what the computer will do, it is not USMC times three, it is US times three.
I figure Q, while insisting all of the syntax has explicit meaning and every single character is chosen carefully with all of history and all of future in mind, is not exactly that careful and consistent. Q is also dealing with a form of war, where predictions and outcomes are uncertain. All that as prelude to our decoding chore being more complicated, because the rules of syntax and construction aren't strict.
What really kills me is the byte-off of
Stage_5:5
because it tells me to start at byte position 5 and go 5 bytes, but of what string???
