I’m also trying to track the number of staff (and staff-like entities: those people the TSU supply staff services to), but the data is unreliable at the moment. We are looking at making this more reliable as time goes by, but we don’t have direct access to the authoritative source for the data (Alesco) and have to relay on ICT Services’ scripts which for some reason include and exclude people apparently at random each day. For what it’s worth on 31 January 2007 the figure was 491, on 28 February it was 458, 5 March it was 435 and 6 March 524.
