The OP is talking about business, so having something done in 2 days versus 4 days is always better. Ignoring everything else, less time is less money.
This is the problem with these kind of discussions. You cannot ignore everything else because everything else depends on 2 versus 4 days as well. Something that's done in 2 days can be exponentially worse than something done in 4 days such that in 6 months you can look back and rationally determine it was better to do it in 4 days.
