Not confused at all, I use ETF for a living. :->)
Again, it is obvious from looking at the slope shapes that the ringing is identical. Were you present for this testing? Do you have the original ETF data files? If so, load them both up again, and adjust the vertical dB ranges so the highest peaks are the same for each graph, and the total span from top to bottom is the same too. In this case you can leave Before as it is, but change After to display 84 dB at the top and 54 dB at the bottom. Then post screen caps here so we can see what really happens in the After graph.
