If so, I have no idea what you mean.

I don't have time to plough through Edgar's posts to find out the answer to this, but (brave soul that you are) you have obvisouly done so... and it is a simple, straightforward question... So, did he answer this in a simple, unambiguous, non-hand-waving, non-pompous, non-spluttering-with-indignation fashion that actually gave you a sensible and convincing answer?
