## 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). 2 of the 8 named sources that could be read published a usable figure; 6 published none and are recorded as not published, never filled in; 0 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 % (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; 17 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 containers-lost count and the container-loss RATE (losses per million containers carried) joined to the marine insurance premium and loss-ratio series, so the price a shipper is quoted can be set beside what the market actually pays out and what actually goes over the side; the series is what makes it quotable - the loss rate is a fraction of a hundredth of a percent, one bad casualty moves the annual number by half, and no page publishes the count, the rate and the premium base together
