What is the Quality report?

Click "Quality report" in the "Ready to publish" card. It lists every puzzle in print order with its level and score, its hardest step, its givens (or cages), its effort and "Proven twice" for its single solution, and confirms that no puzzle repeats one of this book or of your other sudoku books. "Save as a spreadsheet (CSV)" saves the whole report with each puzzle's fingerprint, for your records or to show a buyer how the book was checked.
