Fair enough. Personally, I'd have taken the position that making a straightforward statistical comparison to support an independently-reached conclusion on pricing policy was on the "usable" side of borderline, even given the rules as they stand, but I think under the circumstances I'll take the moral high ground and do my best to maintain a whiter-than-white approach! But write about GW? I don't know the first thing about them! Regardless of whether anyone believes me, I really did just stumble across this a few days ago with nothing more than a vague sense of disquiet that the fairly well known controversy surrounding the company wasn't mentioned - a controversy so well known that even I'd come across it.
