The headline figures (median, minimum, maximum, quartiles) are over ONE figure per source for each breakdown it prices, in hour (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 5 figures, never sentences; 48 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): one row per rule per jurisdiction per worker class, quoted from the instrument with its reference period and its derogations (Great Britain's WTR 1998 and Northern Ireland's WTR (NI) 2016 are separate instruments, and drivers, young workers and special-hazard night work each carry a different number); the derivation the generator needs is the JOIN - every pattern in the library tested against every rule, giving a compliance verdict per pattern per worker class and, across the library, the share of commonly published patterns that breach a limit for an under-18 or an unopted-out adult without an averaging agreement.", "embed": "
