I reply: Making use of pairwise defeat magnitudes is a two edged sword. Yes, it gives information, but it also gives incentive for voters to go out of their way to add more to the defeat strengths that they feel a strategic need for even when the defeat itself is already assured. Substituting Approval measures of defeat strength allows for strategic control without requiring order reversal or collapse. In the zero info case, when there is no pressure for strategy, the sincere approval info is even more valuable, since the sincere approval winner is more democratic than the sincere CW, in a sense that Jobst has made clear.
