Can you elaborate on the structural history of the Shri Sai Satcharita, specifically concerning its chapters?

The overall structure of the Shri Sai Satcharita has a unique history. The preface material in chapter 0 reveals some interesting details about its composition. For instance, it notes that the original 52nd chapter, written by Annasaheb on slips of paper, was incomplete, as the summary and conclusion verses were lost or forgotten. To remedy this, a new concluding chapter was prepared and added as the 53rd chapter. Furthermore, the text points out that the storytelling is not always linear within the chapter structure; sometimes one chapter contains up to five stories, and at other times, a single story is described across two or three chapters.
