Black acrylic sheet: Acrylic Sheet Price Index

Every row is a verbatim sentence read from the named source's own page through our 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).

15 of the 32 named sources that could be read published a usable figure; 17 published none and are recorded as not published, never filled in; 11 could not be read (blocked, dead or unreachable) and count nowhere.

The headline figures (median, minimum, maximum, quartiles) are over ONE figure per source for each breakdown it prices, in GBP (a source's median where its page yielded several accepted sentences for one breakdown), so a page that gives figures for several breakdowns gives one for each and N counts 7 figures, never sentences; 308 candidate sentence(s) were refused by a reviewer with the reason recorded.

The fuller derivation this dataset is chartered to grow into (not yet what the figures above are; they are each source's own published figure as read): the published price per sheet and per square metre for a standard grid (2, 3, 5, 10 mm x clear, white, black, mirror, frosted x 4x8 ft / 1220x2440 mm and cut-to-size) at every supplier that publishes one, cast and extruded separately; minimum, median and maximum per cell, the cast premium, the share of suppliers offering cut-to-size, by country; nobody publishes the cross-supplier grid

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