Epson 8350 Placement

I asked this in the owners thread, but it got buried and unanswered. Thanks for the help.

I have been trying to make sure I have the placement issues correct but it is turning out to be confusing.

Here is what I want to do: 100" diagonal screen, ceiling mounted projector, at 10' throw, dedicated room, no ambient light.

The 8350 user manual says: throw distance of 9.8 to 20.9 feet will enable a 100" screen, and that the max shift from center of screen to bottom of screen is 71.7"

The throw distance calculator form the Epson website http://www.epson.com/alf_upload/land...ce-calculator/
says that at a 10' throw distance 100" screen with projector 24" from ceiling I will get a max shift of 72" from center of screen

The calculator at projector central
http://www.projectorcentral.com/Epso...ulator-pro.htm
says I can get a max 77" screen at 10' throw, but does not address shift. Big difference from the 100" that I want.

I would like to have the projector hang no more that 24" from the ceiling. This puts the lens roughly at 96". With a max shift of 72" (from Epson calculator) that ables me to shift to 24" from the floor. I want to set the screen at 28" from the floor. Is this correct?

Thanks!

Yep, I missed fixing the throw range and then adjusting the diagonal range. Thanks!

Any help with my math for the vertical fixed placement and used of vertical placement is still appreciated.
