Where you are & where you want to be
Only ~1–3% of orders leave a rating. New ratings are assumed 5★. Cost uses the Ratings-campaign tier + this ASIN's price/FBA from the Cost tab.
Pace it against sales velocity
Cap % is your experience-based ceiling, not an Amazon-published limit — it's a configurable risk assumption, not a safety guarantee. "Needed" pre-fills from the Rating Lift tab. Cost uses this ASIN's price/FBA from the Cost tab.
