As clear as the fact that you were wrong about it all along, as clear as the fact that everybody else here told you you were wrong about it all along, as clear as the fact that someone in the IET told you you were wrong about it all along and as clear as the fact that you trying to say you were right then because something is different now makes you look even more ridiculous.
And I don't know about anybody else, but I feel insulted that you thought I'd be stupid enough to accept your "justification"....
