stored read (the sha of the page's visible text; the raw page is mirrored to R2). 7 of the 18 named sources that could be read published a usable figure; 11 published none and are recorded as not published, never filled in; 3 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 GBP (a source's median where its page yielded several accepted sentences), so N counts sources, never sentences; 180 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): two priced series read from the sellers' own pages: steel at GBP per metre per serial size across every stockholder that publishes a price, and calculations at GBP per beam across every engineer that publishes a fixed fee. The derivation is what neither side publishes - the median, spread and cheapest published price PER SERIAL SIZE across merchants (the same 178 x 102 x 19 UB read at GBP 38-55 a metre on the same day), the implied GBP per kilogramme each merchant is charging, the share of merchants that publish at all versus quote-only, the calculation fee per beam beside the steel it specifies, and the movement of both between monthly reads", "embed": "
