Based on the introduction, is there a consistent one-to-one relationship between stories and chapters in the Shri Sai Satcharita?

No, the narrative structure is not strictly linear with one story per chapter. As explained in the preface found in Chapter 0, the relationship between stories and chapters is quite fluid. The text explicitly states that in some places, a single chapter might contain two, three, four, or even five different stories. Conversely, in other instances, one single, continuous story is described across two or three separate chapters. This flexible structure allows for a dynamic presentation of the 150 to 175 stories and anecdotes that comprise the work.
