Percentage point

Following up our story on Sheffield University’s library, where the documents were consistently more than 1,000 per cent relevant, Paul Manning at Glow Safe points out: ‘If a document is 1165.5 per cent relevant, and you want something that is 100 per cent relevant, then surely 1065.5 per cent of it is irrelevant.
‘Therefore, if 1065.5 per cent is irrelevant compared with 100 per cent relevant, this means it is actually only 9.38 per cent relevant.’
