This true, but he acquired a level of knowledge about the world and borderline omniscience of the personalities and circumstances of the main people in France that to me exceeds what a motivated human could be capable of. (I admit maybe I’m just envious or being small-minded.)

In addition to that, the Count’s slaves invariably succeed at achieving the Count’s exact wishes from his often broadly-described requests. At one point he even comments about how that are so attuned to his needs that this type of perfect service is possible. These servants/slaves are in Paris (and working with the highest society) for the very first time, yet they still always manage to carry out the Count’s requests on expedited schedule and with zero hiccups.
