For me, I don’t measure the total airflow from the HVAC unit using a pitot tube manometer at the availability air duct since the whole airflow won't be the same as the sum of the airflow of all related diffusers as a result of resistances in the ductwork.
When developing the proper duct measurement for a certain space, It's important to take into account its features. Look at how warm it has a tendency to be in there and if windows are present. You even have to think about how often a place is applied when coming up with duct sizing.
