As of this morning, Medway is 39th in the league table of completeness (street-names versus OS Locator), with 99.57% of the 2,809 Locator entries now matched (or otherwise reconciled) against names in OSM. A month ago it was 121st and 88.71%. I think the 12 discrepancies still listed are all either in Chatham Dockyard or in Gillingham docks, so we may just end up copying those from Locator/Streetview.
