But given we are (presumably) talking about tournaments with both men and womens competitions, where ticketing, TV rights, advertising etc all come as a "package", is it right to try to differentiate the income they bring in? I'm not convinced that number of sets played is a great argument, because taking account of all the training and travelling, you have to assume they work just as hard as the men year round. Although saying that, I'd like to see the women playing five sets in the quarters/semis/finals of grand slams.
