Once again, I don't understand your point. It's proven by your own typed words.
The whole argument here is purely about semantics.
You have the authority to define how it's supposed to be written only if you are the one who invented fuel injectors
Otherwise it's open to interpretation.You seem convinced that injectors that flow 520cc @ 3 bar and upon raising them to 4 bar pressure should be written as 605cc @ 4 bar . Other people(such as myself) believes it's easier to understand when you have injectors flow at 520cc @ 3 bar upon increasing to 4 bar keep the original flow of 520cc and just specify the fuel pressure has been raised to 4 bar(520cc @ 4 bar).
520cc@4bar = 520 cc at stock 3 bar pressure now runs at 4 bar fuel pressure
605cc@4bar = Total CC of these injectors running at 4 bar.
The reason I think 520cc@4 bar makes more sense is because the majority of cars, especially ours all run stock pressure at 3 bar. So specifying @ 4 bar w/the original flow rate @ 3 bar makes sense because it's obvious to anyone looking at it that the stock fuel pressure was 3 bar.
Anyways, like I keep saying - semantics. I just wish we/JWT would decide on one way of displaying it so no one gets confused. JWT has used both methods of displaying the fuel pressure on their ECUs.

I didn't invent the injector, but I do size flow restricting orifices in my normal job. The italicized section of this statement must be assumed by the reader:
