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