Fair question.
After taking a look at some of your systems (and, rooms) I feel compelled to call my insurance company and make a vandelism claim on my system. "Below average" would be the highest endorsement for my system/room.
As far as those looking for advice, the more data, the better. Sometimes it sounds a bit like: "Hey, I want my car to go faster. What should I do first?" Upgrading/replacing the little cardboard tree hanging from the rear view mirror might cover up some odors, but it's unlikely to improve 0-60 times. Just sayin'.
