I may be wrong but your post no4 about 'robbing cool air' is probably completely wrong..now what is your point exactly?
quite a few threads that wander into the technical side of things have newbie posters who post questions to confirm the answer to an already made up mind. Sometimes you might notice this when hidden in the text is the "given that you are still be beating your wife"
Or worse yet when the answers don't come in the way that they have expected they try and divert the subject rather than listen and learn.
