The decision log
Every check writes one sentence — what it did, what the competition did to cause it, what that beat, and what stopped it going further. Including the checks where nothing moved, and the ones a safety limit stopped.
Below is one day of one account. The sentence structure is the product's. The figures are samples.
Cut the price from $24.99 to $23.45 after the best rival offer undercut you to $23.40 from $24.10, 12 minutes ago. Matching the lowest offer would have earned $0.62 less per day. Featured Offer odds go from 41% to 68%.
Held at $18.99 instead of moving to $17.80 because a safety rule stopped the move. Your minimum price of $18.99 stopped it going lower.
Raised the price from $31.00 to $32.40 because expected daily profit peaks there. These odds still lean on the general model, with only 4 recorded observations on this listing.
Held at $42.50 because prices on this listing have fallen four times in the last hour. Marginary stopped following them down.
Held at $27.95 because the market has not moved since the last check and this is already the best price in your range.
Held at $79.00 because Amazon itself holds the Featured Offer at $76.50. Competing on price here would cost more than it wins.
Raised the price from $44.00 to $46.75 because you will run out 11 days before your restock lands. Selling the remaining 38 units slower earns more than selling them now.
Held at $11.25 because this item has already changed price 3 times today, which is the limit you set.
Held at $119.00 because the move it wanted was $0.02, below the smallest change you said was worth making.
Cut the price from $99.99 to $96.95 after your Featured Offer share fell from 62% to 19% over three days. Rounded down to .95 as you asked. Odds go from 22% to 55%.
No checks of that kind in this run.
Narratives have a maximum length and truncate. Decisions recorded before this feature existed fall back to their stored reason and say so, rather than showing you an empty explanation.
How often it fired, what it did to your Featured Offer share, and what it was worth per day — labelled as modelled, because it is. A rule that fires constantly and improves nothing is a rule you should delete.
Fires most, changes least. Worth deleting.
A brand-new listing has no history, so its odds are the general model wearing a percentage sign. Marginary says so, in the sentence, until that listing has enough of its own measured observations to speak for itself.
The same applies to money. Days where it can see your Amazon orders show observed units; days it can't keep a modelled estimate, clearly labelled. A day with no orders visible is never silently turned into a zero.
Featured Offer share is always measured, never modelled.
