You were lucky you had decent comms because I got some dreadful bore of a Brit on TennisTV who sounded as if he'd have been better commentating on a footie match, and it was obvious too that his knowledge of tennis was somewhat limited. I've come across him once before commentating on a Raonic match (not against Andy) and he managed to pronounce his name in three different ways without ever getting it right! So I did the same thing this time - kept the sound off for much of the match. Didn't get to hear Andy's on-court interview either because TennisTV never show them. It was clear though that the wind was causing a few problems. I reckon Andy probably adapts much more quickly though to the different court conditions than some of the other players because he trains there.
It was nice to see Kim there too, something I didn't really expect with the wedding being so close, but I'm sure all the preparations will be well in hand.
Andy said, precisely that very dry air in I.W. made the ball travel faster but the court surface was slow. In contrast, Miami has much higher humidity (80-85%) ball gains moisture, becomes heavier, but the court surface is much faster.
Now for the scientific approach, which disproves amateur's theories. For those interested in physics and aerodynamics https://fogmountaintennis.wordpress.com/2014/06/05/atmospheric/
Conclusion is that weather conditions affects the players body much more than the ball and/or court.
