Very helpful regarding height (altitude?). The picture even more so. Jealous of your clutter-free room. Since the photo seems to be with a wide-angle lens, hard to guess at ceiling height: 12 ft? 14 ft?
All in all, treating a control room seems more fruitful than a live room- to me, the variables are well nigh overwhelming considering the various types of music, ensemble size, etc, etc. ("great for horns, but stinks on drums").
I believe we also anecdotally evaluate. For example, I'm 6' 1". I typically wear tennis shoes with about a 1/2" heel. That makes my ears about 5'10" from the floor. So when I listen to what's going on in a room and try to do something about it, I'm listening at a distance sometimes of as much as 5 feet from where a mic is placed, for example on kick and (possibly) amplifier cabinets. A good three feet up from where a snare mic may be. Two feet for some horns, 1 foot for female vocalists- you get the picture. There is no way that room is going to sound the same at those varying strata.
It just seems to me that it could be made "perfect" for a particular type of instrument with a specific sound in a precise location with a given mic. But then the ensemble composition and size issues start rearing their ugly heads, and after we have squeezed everybody in and worked out line-of-sight....well, as a previous comment says, work for "pretty good, you won't get perfect anyway."
I am reminded of the photos I've seen of the old Gold Star and the wrecking crew. 30 musicians in a room not much more than 30 feet long. They were just relieved to squeeze them in there. And they cut a few hits too.
