The little/little method makes the chain as long as possible and provides the maximum wrap capacity. If you were to install a cassette with a largest cog that exceeds the manufacturer's recommendation for the max. cog size and wrap capacity, it would not be long enough. In that case, the big/big method would be safer, but the chain would also hang loose when the chain's on the little ring and several of the smallest cogs.
With a Campy 11 drivetrain, there is one chain length that will handle any cassette that Campy offers. There's no need to make the chain any shorter.
