UL Fire Attack Experiment#11 Flow & Move Narrow Fog (What I was looking for, & choose to be there)

I took this video, and this experiment was one I was very interested in. Their was a debate about what a narrow fog consisted of, 20-30 degrees. 30 degrees is mentioned often in texts.
What I was looking for, how good is the "sealing" of the advance for lack of a better term of hallway during flow and move. I expected good, as a 30 degree fog nozzle with no movement has basically equal air entrainment as a 7/8 inch tip rotated at one revolution a second roughly. Fast reversal of flow path, as many know I am a big proponent of door chocks and leavening the entry door open in most cases it is extremely a pro life action.
*door control closed when, where and why are covered in my lectures extensively
How much did the bedroom fire grow, before the 20-30 degree fog pattern got close enough to the door to start suppression. The issue with this pattern is the loss of a hard hitting down range solid or straight stream component, start coverages, cooling and contraction plus capturing accidental deflection suppression water into the room. This is a major weakness with fog pattern during interior operations.
Than final how messy was the fog pattern suppression, with many surfaces touched at once and smaller droplets than my preferred nozzle at the time a 7/8 tip in the hand of a expert tactician.
My ideal SME nozzle firefighter tactician would work a flow and move 7/8" solid stream in smashed "O" pattern into the upper with once in a while floor pick up in the hallway for the best seal possible and higher air entrainment. The solid stream would crash about surfaces, down range starting secondary droplet distributions with goals of better coverage, cooling and contraction started at a distance. While work the hose on the right side of the body with the early left solid stream angle, with a slight pause at just before room entry water into the over head. Followed by a aggressive cork screw "O" pattern upon entry with a full 90 degrees left and right plus nearly 90 degrees up once past the bedroom threshold stream angles with just arm movements. This is a very hard skillset to master, and takes a lot of set and reps, plus it is perishable and requires a high amount of physical effort and fitness.
Without that early stream reach from straight or solid stream starting down range gas contraction and surface cooling plus possible fuel suppression, it to me is obvious why flow and move against no vent fire with a fog pattern was cancelled as a experimental burn. Hence the comment near the end.

Is UL publishing this study on their platform with more data?

That’s awesome, thanks for sharing Dennis.
