Room correction

[JohnnySix]

I don't think it's a good idea to iron out every peak & trough until it lies right on the target curve - some leeway must be allowed to allow them to "ride" the room's natural ebbs and flows, to keep it natural. (Ooooh, listen to me.)

I don't agree with that personally. Leaving anything the room adds that can successfully be corrected defeats the point of doing it in my opinion. I don't feel there's a negative effect to removing everything that can be removed. Filling troughs is the hardest ones to judge and they should generally be left alone -especially in the low frequencies.

Obviously a lot of this is personal preference and Room/speaker dependent. The important thing is you end up with a sound you like and one that's better than you had uncorrected. I've certainly got that now, but there's always room to tweak/improve.

Yes, the troughs are indeed the most troublesome, so if you don't do something about filling them in, then you end up with an overall deficit in the bass. That's probably why I don't like to subtract all the amplitude from the resonant peaks.
