I would point out that you don't see many people, digital or analogue projector owners, posting brightness measurements. That's because the test equipment necessary to get accurate results is quite expensive. Ideally, you would need a light meter that was calibrated to match the CIE standard observer curves, like the Minolta LS-100. These kinds of instruments are not commonly available.
Really it doesn't matter, our own eyes are the final judge. If it's looks bright enough, sit back and relax, everything is OK! Hopefully there will soon be reliable test results for projectors (and other equipment), I believe John Gannon of SGHT is working on a test facility. The test results in HT mags are also not bad for a general ballpark figure, even if they don't necessary have consistent methodology.
