Yes, %d is the correct calculation.
Are you sure EU2 1.09 vanilla text.csv is right?
Maybe some hardcoded values were changed... I'm not sure and even if I was, I couldn't tell.
I have to put this check somewhere in the ToDo list...
EDIT: could you please check differences between EU2 1.09 vanilla text.csv and EU2 1.08 (or older...) vanilla text.csv for the green part?
i do not have 1.08 anymore , but this link below

has the 1.09 vanilla figures in use. Now I know our COT areas do not run at +5 but at +3 like what we use for agceep config text
