Vegetable portions

Should i measure out my veggies before or after i cook them?

example: 7 cups of raw chopped squash cooks down to about 4 cups.

when looking at the carb counts in the google document found in the FAQ, it says there are 2.6 carbs in 1/2 cup. is that 1/2 cup of already cooked or 1/2 cup raw measured out THEN cooked?
