That's exactly the point I make in my article

LF measurements are notoriously unreliable, even in LABS.

That's another point I make in that article. I even argue that testing using waterfalls in a "normal" room is more reliable than in a lab -
comparatively only of course!

I reduced a 34 Hz mode from 1.3 Seconds to 600mS or so using only three SuperChunks. Real world room, Dr. Dan testing. That must count for something.

Yes, it does account for something, and I trust your results more than some of the data I've seen elsewhere! But what density did you use? And did you compare the results of different densities? That's the part I'm most interested in.
