Yet another bass trap question

I am not there yet but I have to make it happen so here’s some questions regarding my future rear corner hanger bass trap. I have enough room in that corner to have it 4’ deep, is it too much ? my understanding is that as far as basstrapping is concern it is never too much , but maybe someone has another point of view. I have read a lot about hanger bass trapping on this forum and some books,and I know there is no data as to how they actually work but but there seem to be some confusion around the way the hangers should be placed inside the trap. Some say one hanger every 8”, other say to place those hanger so the insulation of each one barely touches the next one, or to place them in a heringbone patern. Is just a matter of personal belief :wink: ? or trial and error ? no pun intended really. What would work best. ? Am i better of with a “superchuck” kinda bass trap? Below is a graph of what I am thinking of . Mainly built with 2X3 and not touching the walls and the yet to be built ceiling. The largest panel would be 9’ high by +/-3.5’ deep. All cavities inside the trap would be filled with 3” rockwool but the insulation on the panel themselves would be 3”standard fiberglass. The reason why the front corners of the trap are “cut” is because there will be some high freq absorbers on those walls see CR graph below. There will of course be a fabric to cover it all. Thanks to all.
