Does the Satcharitra's failure to mention other prominent saints from that era diminish its spiritual authority?

The spiritual authority of the Sri Sai Satcharitra, as presented within its final chapters, is not based on its comprehensiveness as a historical document. Instead, its authority is rooted in its divine origin. Chapter 50 makes the explicit claim that 'there is no one other than Sai who makes the words speak' and that Hemadpant is merely an instrument. The book's aim is to lead the devotee to the 'natural state' (Sahaj-sthiti), where the duality of 'I' and 'You' dissolves. The text's authority lies in its effectiveness at achieving this spiritual goal: the purification of the heart through the awakening of devotion to the Saint. As Chapter 50 conveys, this path to non-dual devotion is the 'supreme attainment,' far outweighing the significance of a complete historical roster.
