How does the Shri Sai Satcharita compare to Saraswati Gangadhar's Guru Charitra in terms of length, structure, and the origin of its stories?

The Shri Sai Satcharita shares a similar structure with Saraswati Gangadhar's Guru Charitra, as both contain 53 chapters, including their conclusions. However, the Satcharita is a more extensive work with 9,450 verses compared to the Guru Charitra's 7,300. A key difference, noted in Chapter 0, lies in the source of their content. While we have no definitive means to know if the stories in the Guru Charitra were from direct experience or oral tradition, many of the leelas in the Shri Sai Satcharita were either witnessed by the author, Annasaheb, or were directly communicated to him by devotees who had the experiences themselves.
