I have studied almost all of Evan's and Art's numbers from every projector, because I had to in order to create my projector calculator. Their numbers are all over the place. The Optoma and newer Epsons are one of the few projectors they are close on. Maybe they have better measuring gear this year, but I do not know.
I am not saying the Optoma is a 2000 max lumen projector, I do not believe it is, based on my own research, at closest throw the projector tops out somewhere around 1400+ lumens. The key is the best mode though, it easily can do 1100+ lumens in best mode. Look at the Epson 8700ub, almost 700 lumens from PJC and about a measly 520 from Art. Even worse are the JVC numbers, Art's HD250 vs. RS-10 numbers made absolutely zero sense, a difference of 20%+ on what equates to be EXACTLY the same projector from the same measuring device!
Several of the MFR's have shipped Art and Evan projectors with lightly used bulbs, don't believe me, go check Art's RS-25 (or was it HD250 review). He had whacked numbers until he re-reviewed another unit that he borrowed from a friend who bought one new.
I agree it is dumb of the MFR's to do so, but they recycle the reviewer units, which means they'd need to put a new bulb in constantly. I think sometimes they just leave it in because they figure it's close enough to new, the MFR's really don't think about these things in that much detail, you have corporate bureaucracy in the way usually.
