Explain the readings with a few steady chapters
The dots are 24 measured readings. Add a boundary after a reading to split the trace into chapters. Each chapter is summarized by its mean, shown as a colored horizontal line.
Minimize fit error + boundary fees. Too few chapters miss real shifts; too many chase noise. Each chapter needs at least 2 readings, and you may use up to 5 boundaries. Reach the displayed target to certify your explanation.
