How hard do men serve to women in mixed doubles in competitive, non-exhibition games?
It would be interesting to see if there is any difference in pace of men's serves between when they serve to the male opponent and when the serve to the female opponent.
BTW, is the Hyundai Hopman Cup a true competition or more like an exhibition?
