Probably you came up to the facts, that it's much easier to (1) handle smaller ammount of information and (2) that usage of some kind of automatisation technologies is pretty helpful (in this game: highlighting needed numbers). But did you came up with any idea what's behind those factors here?

Actually, if we would not be in hurry, it would be much more easier to notice that during first round we just had to analyze doubled informational blocks of round two (made same work twice). And in real live this could be x10 or even larger ammout of work. We always think about automatisations, but just stepping out of firefighting state (emergency rushing), can help even more.
