I re-iterate;
"Anyway, I'll sign out on this thread before it descends into an unnecessary but typical Pprune slanging match."
Otherwise you just end up in "thats not exactly what I meant" / " but thats what you said " / "yes, but you were taking it too literally" type exchange from which I derive little enjoyment to be honest. Thanks for an interesting thread up to this point anyway. All the best.
