I don't disagree. Two things. One, keeping track of Renown as per a Harpy in Masquerade lies within the power of the Galliards, without any ST/NPC intervention necessary. Were the PC Galliards to take a stranglehold on Rites of Accomplishment, for instance, this could be accomplished fairly easily.
(Aside, each of the Auspices can wield a shocking amount of power if they work as a unit.)
Secondly, if this information were to be provided from the Spirits to the Galliards, that would be a deal that would need to be worked out in character. It would be necessity be less accurate though, as you're asking the staff to do work, an always dangerous proposition. :p
