Why?......Because too much you your time is spent trolling 200ch and thus your SA is lost when you are too busy typing nonsense. 
It's much more than ch 200. With the help of some top gunners landing 10 victories in a Spitfire requiring my ch 200 and BBS silence for 3 days at a time, per previous agreement, as well as HTC's 8 day mute a couple of times, I do notice a slight improvemt in my flying, but nowhere near the awesomeness of regularly landing 8+ victory sorties.
I think the secret is in all of the items listed in my original post and I intend to find out over the next several tours.
However, there is no denying...
Ch 200 crack is bad, real bad.

There is value though to 200, on occasion. Kind of like an occasional glass of wine is reported to improve health, but a gallon a day, just the opposite.
