Dennis F’n Foley! Thank you. I didn’t fully comprehend the “white water” analogy until the ocean video was shown! 17% per surface area is a sobering number.
We have 6 surfaces within large rooms. If we take 100% and divide by 6 we get 17% per wall. When you are managing reverb in a large room with people in the seats, we can count the floor as treated since each person is the equilavent of 12 sq. ft. of 1/2" carpet plus a 1/2" pad. This leaves the ceiling and the four walls at 83% total. To manage reverb, we have on average surface area treatment coverages that range from 35% coverage, 50% coverage, and 65% coverage depending on the desired reverb times chosen to have an audible impact, Reverb must be managed in the 125 hz. 500 hz. range

Good stuff. Another helpful analogy.
I hope they help with some level of understanding.
