Wolfgang, you said: "Perhaps my post was way too short" and that is exactly why I have suggested that you start a thread with a fuller explanation of what you are talking about. Then you can insert a link to that thread into these type of threads and people will have a better opportunity to understand what you are saying.

The way it is now, you are making brief allusions to something you know and understand very well without giving everyone the opportunity to know more about what you are basing your statements on.
