Talk:2015 Hopman Cup

What is the meaning of scores like [10]-[7]?
I've been watching tennis (well, Wimbledon anyway) for almost 50 years, so I suspect I can't be the only one of our readers who has no idea what the final set score of [10]-[7] means in the Canada-Italy mixed doubles match, and the many similar scores in earlier years. A footnote or a wikilink to an explanation would improve the article for readers like me. Tlhslobus (talk) 00:57, 29 November 2015 (UTC)
