 "methodology": "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). 7 of the 120 named sources that could be read published a usable figure; 113 published none and are recorded as not published, never filled in; 15 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; 56 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 median, minimum and maximum ADVERTISED price of one LEV thorough examination and test across every UK testing company that publishes one, cut by what the price is FOR - a single extraction point, a system of up to five hoods, a multi-system site, a per-employee contract - and by region; and beside it the share of companies that publish a price at all versus quote-only, which is the number nobody in this market publishes and which is what a buyer typing 'lev testing cost' is actually up against. The reads already show the axis exists and the prices are not comparable as quoted: £125 (Eurotecno), £150+VAT first system (121 Health & Safety), £175 (MCG), £180 incl VAT for one system (121's own table), £250 for a single extraction point (Impact), £295 for two systems and fifteen hoods (LEV Leicester), £150-£1,500+ per system as a range (LEVtesting.uk), and £12.50 per employee per year (Filtermist) - eight published numbers measuring eight different things. Normalising them to a price per system and a price per extraction point is the derivation; changed-since on each read is the second",
