I have participated in several double blind A/B of on/off via matched level JVC RS65 at various iris settings and I am very comfortable betting that 99.999% on this forum would not be able to pick out the 30K:1 v the 90K:1 setup on 99.999% of scenes.
On/off is an important metric. ANSI CR is also an important metric.
And I completly agree (and remember my old CRTér too
BTW. when I compared two projector with a on /off of 10000:1 and 20000:1 there was allready very
little difference betwen them and it was allmost only visible on very dark pictures and still there, it was a very small difference - so I having a understanding "problem" with people claiming that they see a "big" difference between say 40000:1 versus 80000:1 on/off ( like I probely would ? with ansi CR on screen
like 500:1 versus 1000:1 ! ).
But anyway I think we all want the "best/ highest" numbers
- we just have to understand and accept that when we hits a certain level, we dont gain very much if anything at all, the biggest problem is to know where that level is
( number terms ) and that I think is easyer to judge by looking you self then create theories based on what you read in various forums and others' experiences, which should always be taken with a grain of salt, because too many other things can come into play.
But of course, it is sometimes used as a rough sorting way, especially if many are experiencing the same problems.
