All you can give are the figures you produce and that’s what’s important. If you have had your car for a while you will know, roughly, with your particular driving style, how far you get on battery only on short journeys or on the motorway and the same on petrol only or a combination of the two.
My daughter has a phev and gets 30 miles on electric when on the motorway and, strangely, 25 miles about town, the reverse would be expected. She is getting about 70 mpg but is almost always driving in electric mode.
