Is there any quantitative data on the different court surfaces?
 
Has anyone done a quantitative scientific study of the behaviour of tennis balls on the different court surfaces? Like, an actual proper study meauring bounce, speed - keeping external conditions constant (humidity, ball type, temperature, wind).

So much talk about the different surfaces, I just wonder if it has ever been quantified.

Would be interesting to see data from Wimbldeon grass 2000 to grass 2013 for example.

Complete waste of anyone's time.
We already know grass is slick and fast, cement slower, HarTru slower, clay slowest.
Within each, there are hundreds of variations and some crossover.

Yes, the ITF have data on court surfaces

There's also data on things like length of games.

I know ESPN occasionally shows various surface differences during matches (change-overs, etc). They just showed the hight difference of the average ball bounces on clay vs grass with fancy graphics and all.

Such studies are conducted regularly by the ITF and USTA to certify balls, surfaces, etc.

But I don't think they will give it to you for free.

Haven't found any for actual years, but here's a comprehensive overview of ball type, spin, and surface.

Yeah we know that you know all there is to know, everybody else is a fool

Thanks, this is interesting.

One thing I noted was the very little difference with bounce height between a flat stroke and heavy top spin stroke on grass court. In fact, average bounce height is slightly less. Maybe this partly explains why Rafa's strokes seem to be less effective on grass. They are slow and just sit up at a comortable height. Would be interesting to see what the velocity is with heavy topspin strokes on grass court compared to clay too.

As for green clay - stuff playing on that.

Well, Suresh? Your stage!
I"m waiting on your answer to post 10, as is the rest of the world as we know it....
While blue is blue, is blue really blue?
