Yeah, I don't buy that study either. I've done extensive lab-quality tests of my own using Panaflex cameras, resolution charts and 35mm film, and I wasn't getting those results. 800 is a believable number, but 500 in the average? Sorry, there's a reason why we don't screen really good VHS tapes at theaters. There is great generational loss, but 500 discernable lines is pretty crappy, I find that hard to be typical, plus there are things other than resolution, which was the problem with early HD.
