I've followed tennis since about 1980. A little off and on in periods, but the interest never went away.
Maybe you can answer to this. I was thinking a couple of days ago whether they were playing multiple matches simultaneusly at the Kooyong Stadium, as it had three courts. It might be interesting to see three matches simultaneously but distracting for the other two courts' players if the crowd starts to cheer after a long rally on one court.
