Conference badge: Badge Lanyard Price Index

Every row is a verbatim sentence read from the named source's own page through the estate's fetch service on the date shown, hash-pinned to the stored read (the sha of the page's visible text; the raw page is mirrored to R2).

3 of the 17 named sources that could be read published a usable figure; 13 published none and are recorded as not published, never filled in; 1 could not be read (blocked, dead or unreachable) and count nowhere.

The headline figures (median, minimum, maximum, quartiles) are over ONE figure per source in USD (a source's median where its page yielded several accepted sentences), so N counts sources, never sentences; 43 candidate sentence(s) were refused by a reviewer with the reason recorded.

Derivation as chartered: the published per-unit price at each quantity break (25, 100, 250, 500, 1,000, 5,000) across every supplier that publishes one, for each of paper badge, PVC badge, RFID badge, badge holder, lanyard and badge ribbon, plus the setup or logo-die charge each supplier adds; the median and spread per unit at each break, the quantity at which the price stops falling, and the share of suppliers publishing a price at all rather than a quote form

43 candidate sentences on these pages were refused by a reviewer; each refusal and its reason is recorded in the review ledger.
