That's because as take-offs are installed along the duct's length the pressure becomes less, necessitating the size decrease to keep pressure up for the later take-offs. Therefore, if the blower/whatever is installed in the middle of the table then the bottom board should slope up closer to the the top surface at the ends. Done this way the puck won't 'run out of air' in certain areas of the board. Like wise if the blower inlet is at one end the bottom board should slope up all the way to the opposite end. I know this will make construction more difficult, sorry, can...
