EDIT: I see you've engaged in the very frustrating practice of editing your comment to reply to my comment. This time with even less etiquette than normal, because you didn't even have the courtesy to flag upfront that it was an edit. I'm not going to play that game by replying in turn, but I do want to call it out as bad form.
