Is this a serious post?
You do not use things to dial in things that you know exist. Your job is to find out what is best for what you are dealing with. Ignore all the other stuff. You'll be glad that you heard this from me. Go on to other parameters, but do not try to dial in one thing from one tweak. That is not how it is done. You listen until you hear what one thing does and put that right.It's barely coherent.
