The truly sad thing is that people probably believe what you say because they don't know better. You do a disservice to this community by posting things like that and by your blind devotion to Optoma. I pray that people do not buy Optoma products based on your recommendations because they are far from reliable. If this were someone without experience or knowledge in these matters, it would be a different story, but you hold yourself out as a technical expert and professional calibrator, besides being Optoma's cheif firmware adviser. That last bit should be in your sig as well so people can make rational decisions about your motives.
You should know that starfields are dominated by on/off contrast, not ANSI. Art's pictures purport to compare black levels. The RS20 was measured around 300 ANSI by Gregr. Why would you take pictures meant for one purpose and attempt to use them for another knowing full well they shouldn't be? It smacks of dishonesty. You also know that screen shots can be made to make a Lumis look worse than a Panasonic AE4000. If you don't know better, you should not be posting.
