Thank you for giving us some actual measurements. Your experience echos what I was expecting after reading the cine4home preview. They measured a native 3300:1 contrast ratio at D65, (which is excellent in itself for LCD, IMO), and got dynamic marks in the same mode at 13,000:1. In maximum brightness trim, their tester got over 60,000:1. With that kind of headroom, with some tweaking they expected that well over 13,000:1 could be achieved while maintaining a usable calibration, and your results again echo that.
I agree with you completely on the benefit of the JVC's native contrast ratio. That being said, from what I have read, the Panny's dynamic implementation is as good or better than any on the market, rendering a seamless effect in actual viewing. While some scenes that bounce from light to dark very quickly cannot take full advantage, there certainly will be many scenes that can. Alas the tradeoff of a dynamic contrast system.
For the money, though, sounds like a winner to me. I am putting it into a constant area setup, so the auto lens zoom/memory/digital shift system is what is putting it over the top versus other options.
I am curious as to your impression as to the lens quality, chomatic aberration, and focus. Also, what do you think of smoothscreen tech on this unit?

I have the projector just overhead and behind at about 16' from a 10' wide High Power screen.
One minor quibble is that the remote doesn't work when I try to bounce it off the screen. Seems like I need to aim it at the projector to get it to work and even just shooting it behind me without taking care to make sure it was pointed close enough to the projector didn't always work. I tried the remote from my AE1000 and that works much better for me, so I've been using it.
I was wondering how well the dynamic iris would work with the Dynamic mode where it has been reported to give a dynamic CR that was about 10x the native CR. I tried the projector like this with some different material and didn't notice bad side effects from such a big multiplier, but also wondered if it was really giving that much. What I discovered with some measurements with basically factory defaults other than that I put it in Dynamic mode (bulb was on high or what they call Normal, Contrast and Brightness were at zero) was that there is an on/off CR range it will do if you only include right about when a full black image goes up and what it will do if you give it some time. At a little distance from the projector I measured white at about 11,000 lux. When I then put up a full black image and tried to measure what it was giving in the first second or so I got 1.67 lux. Then I counted in my head and estimated it took 10-15 seconds for the iris to slowly close down to settle at .24 lux. So, about 6600:1 on/off CR right away and about 46k:1 after some time.
I'm not reviewing projectors anymore, but if I was I think I might do something like report the on/off CR a projector with a DI can do within maybe 2 seconds and what they can do if given a lot of time with a blackout screen.
I should mention that since the projector was showing steps above reference white (video 235) out of the box, I'm sure I could have raised the Contrast settings and gotten somewhat higher numbers than above by crushing some of the stuff above video 235. I didn't measure any colors or adjust them in the menus though.
As far as ANSI CR, in Dynamic mode I measured 330:1 and for a modified ANSI CR of just measuring the center 4 rectangles (I think this is what Greg Rogers does) I measured about 250:1.
I've done some experimenting with the frame creation. I was checking out the fairly new Blu-ray of Hell Ride
and there is a pan right at the beginning that shows the differences really well. I'll need to try it some more to see how many side effects there are, but I think I could get used to not seeing jumpy images on pans.
Overall it seems like a really nice projector for the price to me, but the on/off CR stuff I measured pushes me much more toward the RS20 for my theater room, since I don't consider on/off CR that takes 10-15 seconds to get there to really be much of a feature (especially when there isn't enough CR before that to blackout to my eyes most of the time) and expect the close to 40k:1 native on/off CR I think I'll get with the RS20 to give some nice visible improvement. I may keep the AE3000 as my second projector to use in my bedroom and move to another setup though.
