EvidenceEvidenceWhat kind of fact this row is. A completed sale, a live ask and a calculated guide price are three different weights of evidence about the same number, and this column is the difference between them.
ObservedObservedThe day the fact was read — not the day the underlying event happened, and not today. An old date is an old reading.
AgeAgeHow long ago this row was read, as of the moment the page was computed.
ConfidenceConfidenceHow much weight this row carries where it feeds a model, from the resolver that matched it. Lower means a looser match or a thinner source, and a low-confidence row is reweighted rather than dropped.
ModelledModelledYes = a CALCULATED value (a guide price, an estimate); No = something actually observed (a sale, a listing, a census count). A modelled row is evidence about a model, not about the market.
Live askA copy offered for sale right now. An ask is what a seller wants, not what anyone paid — it bounds the price from above until it clears.

Method▾
Every price is that product’s newest stored daily bar, picked by the same precedence the chart above uses — a real observed sale beats a modelled guide, and the guide stands in only on days with no sale. Per-pack divides by the PUBLISHED pack count and is withheld wherever that count is not on file, because a guessed denominator makes a fabricated price. Products the set has but we cannot price keep their row, with a dash.

A wholesale ask is a distributor’s price for a whole lot — freight, minimums and any trade terms sit behind it — and is not a price a single box trades at. Links go to the distributor’s own page; nothing here is an affiliate link. Per-pack figures divide the lot price by the pack count the distributor published, never by a guessed one.
