I wasn't the first to move beyond the scope of specifications. We all here understand that specifications are just specifications and that they may cause vastly different results in real life.
It was in fact You guys who started talking about grey screens, lamp modes etc. So:
Should we talk about the specifications in an isolated sense or not?
Because if not - please tell me what can be gathered from the specifications concerning the BenQ.
You fail to see that the place I'm going with this is that the specifications we are discussing, the traditional OR my variation, are very, very schematic and have extremely little to do with the reality of each machine - and THEREFORE the damage that You suppose that the alternative would do is next to zero.
Why? Well, simply because there IS SO MUCH MORE to know and find out about each new projector so when one has done that, one has moved waaaaaaay beyond both the traditional spec and the alternative.
Again (and please read this sentence with the rest of this post in mind): The alternative spec:s are for average-Joes that will never worry about anything but getting the pj with the best numbers. Once he moves beyond that, he will soon find out that most of the stuff in the specification is *VERY* scetchy and should be interpreted with great care - and that goes for all data (except maybe the weigth and dimensions of the pj
Also - the question that You answer: "Exactly. Your method, in idealized circumstances when used and understood by advanced videophiles, will add absolutely nothing new that we don't already know." to above ONLY is valid for people other than average-Joe.
In fact, it's only valid for people who have the projectors that he wants to compare at hand and who has a colorimeter and the knowledge to use it correctly. And how many people are we talking about then? Well, in the US I don't know, but here in Sweden, we are talking about maybe 3-5 guys. Myself excluded, simply because I don't have access to all the pjs that I'd like to comare.
This is why You're living in a dream world.
