I watched that video, while it would be nice toy for me, I do not feel it could do better than the App as I have seen no evidence it could do so. Since the license if not transferable, I will not be purchasing the license until my next AVR or AVP upgrade for sure.
By the way, I recently moved my couch and felt the bass off a little when was too busy to re-run Audyssey until two days ago. So I took a little time to do it and then use the App/Rat to tweak for about an hours.
The results this time are not as good as my last run/tweak that gave me less than +/- 1 dB 20 to 130 Hz vs this time's +/- 2 dB (20-300 Hz though), but last time I spent many hours to get there.
So I would say if one is happy to tweak the results only to the apparent diminishing point of return, that is, +/- 2 to 2.5 dB, it would likely only take 1 to 2 trial using Rat.
I played with Dirac Live's 2 channel trial version about two years ago and like its UI, but there was no way for it to get better results than XT32, except it did do slightly better based on the impulse response.
Here's the results after just two trial with the App/Rat, the whole process should take less than an hour to do for the front left and right channels:
