I thought the goal was to have the projector as close to the screen as possible to increase brightness is that not the case?
Not sure if you read my post, but I'm not a fan of having the projector as close to the screen as possible. So long as the screen isn't huge (or has negative gain) then I prefer to have a long throw which maximises contrast, it also helps the A-Lens to work to it's best advantage since it will minimise pincushion such that a curved screen isn't necessary (it probably will be at minimum zoom distance). I can hit my target fL of 15-16fL in 2.35:1 mode with my X35 in low lamp, minimum zoom and the aperture set to -8/-9 so I have plenty in hand for lamp dimming (though it's barely dimmed from new and I'm at 150 hours now). FWIW for the same fL in non lens 1.85:1 viewing I have to close the aperture down to minimum at -15, so my modest 1.5 gain screen helps, but I've no need (or desire) to move my projector closer.
Each to their own though.
