exact and there may be gaps between some of the tabs and the base however it may nevertheless be seen that substantially discrete openings 47 are nevertheless provided as may be understood selection of the various vent hole and baffle sizes positions and relative locations is but one important feature of the present invention this includes not only the various elongate baffles and vent holes but also the ventilation openings 39 which are configured at least in part to balance the air flow into the bottom of the vent with the airflow out of the front edge of the vent through the vent front edge vent and discharge openings 47 see fig2 as may be understood the u201c total area in u201d of the ventilation openings is to be balanced relatively to the u201c total area out u201d for a given air flow direction u2014 flow out or in to the structure which may differ depending on conditions reference is now made particularly to fig6 and 7 which illustrate the manner in which the vent assembly 10 is configured to provide improved airflow given the limitations of a relatively thin and flat vent while also providing improved water and debris resistance and control the base ventilation.
