By sliding out the lens he achieves a higher ansi reading pretty close to the target.
Now reference (from a video standpoint) is a moving target. For constant image width Odyssey's system is reference by a long shot. For CIH the paradigm will shift soon, as soon as the post production reference Barco's leave the gate, then a uhp powered 3dlp/isco3 or a cermax powered 3dlp/isco3 can no longer be considered reference, reference in compact projection maybe.I don't think he has any presumptions of his video chain being totally compromise free, he understands the limitations of UHP and decided he could live with it. I believe though he has become an ANSI convert having lived without it for so long.
A UHP lamp DOES NOT AGE the rgb values linearly. This RGB interactions over usage time and percent of power boost need to be charted and understood.
I believe that Art and everyone else with these uhp projectors will require re-calibration every 200-300 hours depending on the lamp power mode.
On the other hand the real xenon projector will give a flat spectral response for 1,000 hours. Not to mention that the digital cinema units allow you to use the TIP7 calibration system, that when properly setup with a 5nm accuracy acoutred spectrum radiometer, as opposed to the ubiquitous 8nm (the suposedly current state of the art as per JK and the ISF) will yield you the most perfect drift free color possible. This mostly has been covered by Odyssey in his posts.
The fact that an anamorphic projection looks damn good and very filmlike ignores the fact that 3dlp has inherent more ANSI and thus more potential MTF than film at the 2k resolution format. The superior image will happen with a real xenon lamp and a high quality digital cinema servo zoom/tilt/focus lens.

I think you need to stop frequenting the humour and sarcasm usenets, and invest some money in R&D outside of the scope of home automation and control. Specifically it would not hurt you to attend SHOWEST.
If you did, and you poked around, you would learn why your idiotic statement is not possible in a 12 degree dmd-tilt world (that we currently live in).
ANSI will not increase past 975 with such little tilt angle as light will inevitably stay in the tube. But fear not, my reference ansi and mtf image has always been the same, September overlooking Magens Bay in St Thomas USVI, where the rapid trade winds move the clouds at a frenetic pace allowing the spectator to sample a wide range of light and color in a sitting.
Magens Bay therefore has to be considered a reference image, not a cloudy day in seattle, or the view of the fields of siberia. In those realities you are mostly talking about varying levels of gray.
To recreate that dynamic range and colorimetry a 12 degree tilt dmd suffices.
I can attest, 975 ansi is fine, you sir are the imposter.
