I don't disagree with you at all, ahab. My suggestion is that requiring an additional 10 easily accessible (if you believe CC timelines) as a stall tactic by the FDA wouldn't be all that effective. That's what makes me think that this was something different altogether. If they FDA wanted to seriously stall, then they require another 30, or don't accept the current 40, or require a new trial... Stalling things by a couple weeks isn't exactly a coup de gras.
My opinion, of course.
