With all due respect, I simply identified an apparent inconsistency in what you were saying and asked you to clarify it. I honestly can't see how you could have a problem with that. If you re-read this thread you will see that I have gone to considerable lengths to deal with your original, quite technical query in as comprehensive and detailed a manner as is possible on a board such as this. If I were "impatient" or "abrupt" would I have bothered? Perhaps given all the gratitude I have got from you, perhaps I would have been better off had I "impatiently" ignored your question in the first instance.
I think this is about as much sense as will come out of the thread so I'll finish it at that. The answers given have been helpful, thanks. I hope others found it useful too.
