Scenario-grid sensitivity counts by price
Original analysis by Alisson Bento. Source: Amazon KDP policy snapshot, 28 October 2026.
Deterministic Amazon.com USD model; zero VAT and 70% eligibility assumed; snapshot 28 October 2026. MB means hypothetical platform-priced MB, not upload-byte size. Half-up/half-even rules are illustrative; counts are chosen scenarios, not authors, sales or income. 11 price-level summary rows. This is a summary, not the full 550 heatmap cells or 5500 fine-grid cells; both exact datasets are downloadable.
