The maximum pop-out maximum seems very consistent.
I tried an experiment yesterday with the end credits of haunted castle. The cupid or what ever it is - is intended to hover right in front of you at the movies. On my tv it hovers about a foot in front of the screen. If I move closer - it doesn't appear to move (retract) very much. When I get close enough - it appears that I can touch it (about two to three feet away from the screen). I really feel the difference is screen size and the maximum pop-out distance is directly proportional to that size. I know this may go against the quoted science but this is what I observed.............
I just watched the end of Haunted Castle (free on Comcast On-Demand) on my BDT210/Sharp 835U 3D TV. Cupid comes out of the screen ~ 50%. So when I'm sitting 6ft from the TV, he is out about 3ft. When I'm 3ft from the TV, he is out about 18in and I can "touch" him. If I get closer yet to the TV, I can actually get my hand behind him. BTW - It is funny watching him move as I move closer and further away from the TV screen.
So that leads me to believe that in order for a movie theater to get an image close enough for me to reach out and touch it, the pop-out must be a much higher percentage. If I'm sitting 50ft from the movie screen, to get the image 2ft in front of me, that would be a 96% pop-out (the image would be 25ft away with a 50% pop-out).
BTW - Haunted House is an excellent movie to experiment with pop-outs. The first time I watched it, I didn't notice the cupid because it "pops-out" after the animated part of the movie is over. When the rock concert scene comes on, the cupid floats in front of you for over five minutes. The whole time he is popping credit bubbles with his foot. Lots of time to see what happens to pop-outs when you change seating distance and viewing angles. You can also see content generated cross talk visible on bubbles on the extreme left and right sides and how the cross talk goes away as the bubbles move to the center. There is no cross talk on the cupid because he is always in the center of the screen.
