Well that kind of jives with what was posted (by Erik?) earlier, that a On-Off/ANSI ratio of 9 is about optimal, where one is holding the other back if it deviates from that.
For example, with my IN76, it's about 3x, and the higher On/Off makes a big difference, the low On/Off is holding the IN76 back more than the ANSI is benefiting it.
The RS1 is more like 45x, and when put up with something else, it's clear the ANSI is holding it back.
Looks like there are some interesting analysis' that can be done, for example:
Drop the "20k" On/Off to 5000 (5x), and the "RS1" regains it's lead, or if the RS1 somehow managed 400:1 ANSI, same result.
All in all, I think what we've found, or are finding, is very interesting and very valuable information in these threads.
1) It seems the measurements are validating the models.
2) 1a?) The models seem to correlate well with "real world" content/results.
3) The models allow easy, and apparently accurate, comparisons of projectors in ways we've never been able to quantify before.
I'm actually beginning to think that the really important thing that's been/being done here, is not the gathering of new data for projectors, but the investigation of how the current data (On/Off, ANSI) relates to real-world images and projectors.
