My HC6000 is in route and I want to be ready when it gets here. I want to get the ceiling extension setup plus the screen installed. Mitsubishi has a calculator, but does not have the HC6000 in it. ProjectorCentral has one also. I need the screen location from the floor or ceiling plus the throw distance from the screen.

Which one would be the best for giving me the height from the floor or ceiling and the throw distance?
