I *do* have before and after graphs. Mostly I was concentrating on the impulse graphs to try to get things down by 20db within 20ms. I'm not quite there yet, but the overall drop is huge. I actually haven't really looked at SPL over the spectrum recently...nor have I measured with Audyssey turned back on. I should get around to doing that.
Anyway, I'll try to find time to put together a post with the before and after graphs soon. They aren't subtle.
Posting before/after room measurements are probably the most helpful, encouraging and inspiring posts we can make. Not to single you out, we should all do this.
To start this tradition, here is my first FR for the right channel. I had mild treatment at that time. Additionally, I have changed main speakers and added subs as well.

Red = Then
Green = Now
My ETC data only goes back about a year, and look similar to now, so I didnt post them.
