Original · 93 words

A local library tested a four-day schedule for six weeks. It kept the same 40 weekly opening hours, closing Wednesdays and extending Monday and Thursday evenings. Visits rose from 1,200 to 1,320 a week, although Wednesday visitors had to change plans. Staff reported fewer interruptions, but productivity was not measured. Longer evenings may help people who work during the day; this does not prove every library should open fewer days. Before making the change permanent, the team will survey residents, compare costs and repeat the trial in winter, when travel habits may differ.

First rewrite

A town library trialled a four-day week for six weeks. It maintained 40 hours a week, shutting Wednesday and opening longer on Monday and Thursday evenings. It saw a increase from 1,200 to 1,320 visitors a week, although those going on Wednesdays had to adapt their routine. Staff said it was less disruptive, but efficiency data was not collected. Having more evening hours can be a boon to part-time workers, but does not necessarily mean all libraries should be open less often. The team will survey residents, compare expenditure and repeat the experiment in winter when people are less likely to stay at home.

One short English sample and the first captured output in the stated mode. Paid models, long documents, external detectors and live integrations were not tested. Pricing is a dated snapshot; documentation is not an end-to-end integration test.
