even if it looks not so smooth, it sounds really good. And those two continue "blades" at 80 and 160Hz are just external noise from an UPS generator.

Everything is relative. If you got rid of or minimized the resonances it would sound substantially better. But very few know how an almost "resonant free" system actually sound like.
Understand that my technique is very good for LF absorption while not absorbing much at HFs. That was my intent. Absorption panels tend to work in the exact opposite manner, that's why I don't use them. Small rooms needs lots of LF absorption, but not at HFs since almost everything in the room is going to do that job already. In a fairly well sealed room the LFs will get out of hand unless there is some absorption.
That depends on how deep the dip is. A shallow one is no problem, but a true null cannot be eq'd. A deep null could only occur if there were only two interfering sources exactly out of phase. If there are more sources, like I recommend, then deep nulls are virtually impossible to happen and hence the entire LF spectrum can be corrected for three sources.
This is not actually true - in the modal region (you have it backwards.) It is true above that region, but in the modal region the sound does not change much from location to location. Far less than it does above the modal region.
Yes, but higher up the spectrum it isn't as noticeable. I can move a few inches in my room and a 50Hz dip comes and goes, I only have two subs though, three does seem the way to go out of all the options.
Correct. Are you suggesting a 50Hz tone is cancelling (or not) with the radiant mains field in my room?? 
Computers are noisy environments. I've had issues at that frequency. Depending on what I am doing, sometimes it will show high in magnitude, sometimes it will vary from shot to shot as if taking an instantaneous value within a cycle.
