The 119" high power screen (52x92) for my new AX100, works out to a peak brightness of 49 ftl!!!
The center seat is on a couch with the sides of the couch reclining - those will be the most used seats at 13 degrees off axis, the brightness should be about 30ftl. Is that also considered too bright? For the remainder of the seats, (rarely used, and when so - for movies and probably at night) the brightness quickly drops to about 14ftl. How bad is that? Thoughts on this?

Throw distance on PJC calculator does not appear to affect calculated brightness, so I have not factored that in. I will be throwing from about 16.5 feet. From this discussion I gather there could be a significant decrease since I'm not shooting from the closest possible position.
The other option appears to be the 106' HCMW, which drops the brightnesses down to 25, 22 and 19 ftl for the different seating mentioned above.
I am guessing that I want at least 22 ftl, since this is the point at which the PJC says it's OK to have some ambient light.
How bad is 14ftl in a light controlled room. I really like the properties of the HP but want the option of sometimes having the "outside cone" seating..
